Well basically xmlNewChild() create a new node in the parent namespace if no namespace is provided. Try to setNs(None) on the resulting node. Okay the API is a bit weird, but changng it now is likely to break stuff...

You parse document, there is no notion of parsing a fragement. Many thing in parsing are contextual like namespace, base, entities, etc... I really suggest reading the specs before trying to do this kind of things. > Pointers to existing (sample) code that does these things would be > perfectly acceptable, but please don't point me to sample code that > doesn't do what I asked for. :) The point is that what you ask for really doesn't match any standard processing it it will be custom. The closest to what you seems to have in mind are: http://xmlsoft.org/html/libxml-parser.html#xmlParseBalancedChunkMemory and http://xmlsoft.org/html/libxml-parser.html#xmlParseInNodeContext but really it's outside the definition of normal document parsing as defined in XML-1.0 > The doc is not very extensive on libxml, > and so good sample code is kinda required.

We want it to be possible for the user to cancel an operation if it is taking too long in Yelp[1] (GNOME's help browser). Shaun has found that setting the xsltTransformContext->state = XML_STATE_STOPPED in the extension element function, the xsltApplyStylesheet() call then returns immediately (after the ext. element function returns). My question is, if we cancel the process in this way, is the transformContext and result document in a consistent state where we can just call xsltFreeTransformContext() and xmlFreeDoc() and not leak large amounts of memory? [1] We are investigating making the DocBook stylesheets work on a single "chunk" instead of processing the whole DocBook file in one go, but in the meantime are investigating stopping the xsltApplyStylesheet() call.

I'm using the C RELAX NG API with xmlTextReader. I'm trying to register error callback functions for validity errors encoundtered in my *instance* document. I seem to be able to register handlers for all types of errors when parsing my RNG schema, and also well- formedness errors in my instance document. I can't seem to register error callbacks for *validity* errors in my instance doc as mandated by my RNG schema. What's weird is that I do see these errors being reported to the console! These are the errors I want to receive in my C callbacks, but I can't find any way to register for them. Can anyone help? I've tried scouring xmllint.c for examples, but I just don't see where this happens. Other than that, I can't find any examples online. Here's what I'm doing: char *docfurl = ".../golf.xml"; char *schemafurl = ".../golf.rng"; // RELAX NG Parser Context xmlRelaxNGParserCtxtPtr ctxt = xmlRelaxNGNewParserCtxt(schemafurl); xmlRelaxNGSetParserErrors(ctxt, (xmlRelaxNGValidityErrorFunc)rngErr, (xmlRelaxNGValidityWarningFunc)rngWarn, NULL); // Parse schema xmlRelaxNGPtr schema = xmlRelaxNGParse(ctxt); // create reader xmlTextReaderPtr reader = xmlNewTextReaderFilename(docfurl); // associtate schema with reader xmlTextReaderRelaxNGSetSchema(reader, schema); // register some callbacks (apparently not the right ones) // never seems to be called xmlTextReaderSetErrorHandler(reader, (xmlTextReaderErrorFunc) readerErr, NULL); // handles well-formedness errors in instance document xmlTextReaderSetStructuredErrorHandler(reader, (xmlStructuredErrorFunc)structErr, NULL); while (xmlTextReaderRead(reader)) ; NSLog(@"done. isValid: %i", xmlTextReaderIsValid(reader)); The callbacks you see registered here are usually called for different things, but none for validity errors in the instance doc caused by non-adherence to my RNG. The reader *does* correctly report whether it was valid or not at the end, which is good... but I want to receive the individual validity errors too. Can anyone help?

Seems to be a bug in the reader implementation, when registering an error handler on the reader it should also propagate to the associated schemas, I don't think you can fix it from the API since the reader RNG validation context is not accessible, so please bugzilla this, this should be easy to fix. thanks, Daniel -- Daniel Veillard | Red Hat http://redhat.com/ veillard@redhat.com | libxml GNOME XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | Rpmfind RPM search engine http://rpmfind.net/ From veillard@redhat.com Sun Jul 2 05:16:54 2006 Return-Path: X-Original-To: xml@gnome.org Delivered-To: xml@gnome.org Received: from localhost (unknown [127.0.0.1]) by menubar.gnome.org (Postfix) with ESMTP id 01BFE3B00EB for ; Sun, 2 Jul 2006 05:16:54 -0400 (EDT) Received: from menubar.gnome.org ([127.0.0.1]) by localhost (menubar.gnome.org [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 22838-10 for ; Sun, 2 Jul 2006 05:16:52 -0400 (EDT) Received: from mx1.redhat.com (mx1.redhat.com [66.187.233.31]) by menubar.gnome.org (Postfix) with ESMTP id 897B43B017D for ; Sun, 2 Jul 2006 05:16:52 -0400 (EDT) Received: from int-mx1.corp.redhat.com (int-mx1.corp.redhat.com [172.16.52.254]) by mx1.redhat.com (8.12.11.20060308/8.12.11) with ESMTP id k629Gp4N004715; Sun, 2 Jul 2006 05:16:51 -0400 Received: from devserv.devel.redhat.com (devserv.devel.redhat.com [172.16.58.1]) by int-mx1.corp.redhat.com (8.12.11.20060308/8.12.11) with ESMTP id k629GpEJ002528; Sun, 2 Jul 2006 05:16:51 -0400 Received: from devserv.devel.redhat.com (localhost.localdomain [127.0.0.1]) by devserv.devel.redhat.com (8.12.11.20060308/8.12.11) with ESMTP id k629Gotu003679; Sun, 2 Jul 2006 05:16:50 -0400 Received: (from veillard@localhost) by devserv.devel.redhat.com (8.12.11.20060308/8.12.11/Submit) id k629GgNA003677; Sun, 2 Jul 2006 05:16:42 -0400 Date: Sun, 2 Jul 2006 05:16:42 -0400 From: Daniel Veillard To: ensonic Message-ID: <20060702091642.GR1483@redhat.com> References: <87r715yv8x.fsf@nicferrier.tapsellferrier.co.uk> <67bf80b044bd99df0167a848f3f2996b@hora-obscura.de> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <67bf80b044bd99df0167a848f3f2996b@hora-obscura.de> User-Agent: Mutt/1.4.1i X-Virus-Scanned: by amavisd-new at gnome.org X-Spam-Status: No, score=-1.977 tagged_above=-999 required=2 tests=[AWL=-0.382, BAYES_00=-2.599, MANY_EXCLAMATIONS=0.775, SPF_HELO_PASS=-0.001, SPF_PASS=-0.001, TW_BX=0.077, TW_IB=0.077, TW_PM=0.077] X-Spam-Score: -1.977 X-Spam-Level: Cc: xml@gnome.org, Nic James Ferrier Subject: Re: [xml] Namespaces!

Still not nice though. I don't like this, this does not match any internal processing. This is one specific weirdness of the API though IMHO probably not that much of a problem. In general either you use namespaces or not. If you use them and you compose vocabularies they will all be namespaced, adding a non-namespaced island in the middle of a namespaced document looks like someone tried to retrofit an old vocabulary in a recent framework, I really don't expect this to be a common case. The most common when you create a child of a namespaced element is to reuse the same namespace (i.e. same vocabulary) unless you switch to another namespaced vocabulary.

PSVI is not part of the original document and libxml2 is an editing toolkit initially. Now to be constructive one could suggest an API extention to do that extension on a case by case basis.

However, adding default or fixed attributes to the validated instance, regardless if it's a node tree or processed with a stream-based technique, is not stated by the W3C XML Schema specification. What you really want is PSVI (http://www.w3.org/TR/xmlschema-1/), which would allow to lookup default/fixed attributes. Currently PSVI is not supported. Additionally, I wonder how we should provide PSVI with a streaming API? But we added the automatic creation of default/fixed attributes for the non-streaming API, so if you would be so kind and investigate if it's possible with Libxml2 to fire additional xml-reader events for default/fixed attribute, then this would be a good first step to have it implemented. =20 > I came to the conclusion that it currently makes no sense to > do some implementation based on XML schema within libxml2. Is=20 > this correct? Well, every question needs it's appropriate answer: Yes and no. If you provide reports and test cases for the areas which don't work for you, plus investigate the spec to allow you a broader assessment of Libxml2's implementation, then you'll surely will be gratified with a working solution. If you cannot afford this additional time-consuming overhead on your side, then, I fear, you made contact with a term that's called a "bug", or "feature request", and, unlike a Bose-Einstein condensation, where multiple bosons can share the same quantum state, a bug is not a non-bug. > If you see a way to do some development, I would ask you to=20 > send me some example code or some hints where to find example code for > "how to read xml files based on xml schema" using libxml2. > What are the future intentions with respect to XML schema support? I think we intend to implement the missing areas. PSVI is a different story, which we need to consider well when implementing XPath 2.0 and XSLT 2.0 in the future, since PSVI will have to be a part of those new technologies, and we don't mant to make API-related mistakes, before we see the whole picture; and that should be when XSLT 2.0 & Co. become a W3C recommendation. > By the way, the DTD based functionality works fine. >=20 >=20 > Thanks in advance and best regards > Manfred Rahmig Regards, Kasimier From liam@holoweb.net Mon Jul 3 14:51:51 2006 Return-Path: X-Original-To: xml@gnome.org Delivered-To: xml@gnome.org Received: from localhost (unknown [127.0.0.1]) by menubar.gnome.org (Postfix) with ESMTP id 1A2843B0184 for ; Mon, 3 Jul 2006 14:51:51 -0400 (EDT) Received: from menubar.gnome.org ([127.0.0.1]) by localhost (menubar.gnome.org [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 02050-03 for ; Mon, 3 Jul 2006 14:51:48 -0400 (EDT) Received: from hd-t1637cl.privatedns.com (ip-209-172-34-239.reverse.privatedns.com [209.172.34.239]) by menubar.gnome.org (Postfix) with SMTP id A22133B0125 for ; Mon, 3 Jul 2006 14:51:47 -0400 (EDT) Received: (qmail 3468 invoked from network); 3 Jul 2006 18:52:32 -0000 Received: from localhost (HELO ?127.0.0.1?)

The best time to look at XPath 2 and XSLT 2 is now: they are Canadiate Recommendations, and if there are things that can't be implemented, we want to know *before* they are final Recommendations. Of course, we already have quite a few implementations of XPath 2 in XQuery implementations, and the interoperability story there is pretty good, it turns out, but even so I strongly encourage you not to wait.

FWIW, I think the same. I have/is implementing XQuery 1.0/XPath 2.0 and the specs are very stable, especially the latest drafts. Close to all changes done and the ones currently queued are editorial issues. I have actually found it an advantage to implement while the specs have been maturing, because the changes haven't been large enough to be a burden to align with, and it have given the opportunity to report & fix bugs in the specs which one discovers first when implementing. It wouldn't surprise if it would be a long wait for the Rec "stamp", since the W3C machinery can drag things out in this area. (My personal views.)

This bug does *not* exist in 2.6.26 as I reported. I *does* exist in 2.6.16 which I believe is the version that shipped with Mac OS X 10.4 Tiger. I was using this built- in version (2.6.16) mistakenly when running my tests. I had thought I was using 2.6.26, but I was wrong. The bug no longer exists in 2.6.26 as far as I can tell. Apparently it was fixed sometime between the two versions. So my humble advice to anyone wanting to use the RELAX NG features of libxml2 is to use the very latest version: 2.6.26. In 2.6.26, the "xmlStructuredErrorFunc" reports RNG validity errors. I had assumed that the "xmlTextReaderErrorFunc" would report these, but I guess I was wrong about that too. Although... perhaps *that's* a bug? ;) I've updated the bugzilla bug: http://bugzilla.gnome.org/show_bug.cgi?id=346414 Thanks, Todd Ditchendorf Scandalous Software - Cocoa Developer Tools http://scan.dalo.us On Jul 2, 2006, at 2:11 AM, Daniel Veillard wrote: > On Sat, Jul 01, 2006 at 10:19:15PM -0700, Todd Ditchendorf wrote: >> Can anyone help me with registering RELAX NG validity error callback >> functions? > > Seems to be a bug in the reader implementation, when registering an > error handler on the reader it should also propagate to the associated > schemas, I don't think you can fix it from the API since the reader > RNG validation context is not accessible, so please bugzilla this, > this > should be easy to fix. > > thanks, > > Daniel > > -- > Daniel Veillard | Red Hat http://redhat.com/ > veillard@redhat.com | libxml GNOME XML XSLT toolkit http:// > xmlsoft.org/ > http://veillard.com/ | Rpmfind RPM search engine http://rpmfind.net/ From liam@holoweb.net Mon Jul 3 22:46:42 2006 Return-Path: X-Original-To: xml@gnome.org Delivered-To: xml@gnome.org Received: from localhost (unknown [127.0.0.1]) by menubar.gnome.org (Postfix) with ESMTP id 5C1023B012A for ; Mon, 3 Jul 2006 22:46:42 -0400 (EDT) Received: from menubar.gnome.org ([127.0.0.1]) by localhost (menubar.gnome.org [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 29085-04 for ; Mon, 3 Jul 2006 22:46:39 -0400 (EDT) Received: from hd-t1637cl.privatedns.com (ip-209-172-34-239.reverse.privatedns.com [209.172.34.239]) by menubar.gnome.org (Postfix) with SMTP id 0933C3B0106 for ; Mon, 3 Jul 2006 22:46:38 -0400 (EDT) Received: (qmail 1035 invoked from network); 4 Jul 2006 02:47:25 -0000 Received: from localhost (HELO ?127.0.0.1?)

But it's good that you found the workaround in the more recent versions as it's not a completely trivial change (though it should not be hard to do).

Damn, I knew somehow that writing about XPath 2.0 and XSLT 2.0 would lead to trouble :-) I think an implementation was not yet planned, plus I don't know if we'll have enough human recources. I would love to help here; since I'm already trying to refactor Libxslt, which should also be helpfull for a later XSLT 2.0 implementation, I volunteer for that side (Bill, what about you?). It would also be nice to have some people outside of the core-team involved; I always wondered why there isn't much more input from other people - are we so scary? I don't know if Daniel has enough time to plan that beast; if there would be more helping hands we could take over more burden from him.

I can't code, but I will gladly discuss different implementation approaches, interpreting the specs, performance stuff, and so on. So, I'll drop into discussions on 2.0 stuff if it isn't too tied to libxml2 internals. I think implementing XSL-T 2.0 starts at implementing XPath 2.0, because that's the most intrusive part. The differences between XSL-T 1.0 & 2.0 aren't that invasive, while XPath 2.0 carries a whole new data model and a type system.

Write an XPath test app and debugg the parser and evaluation code, while switching back and fro to the specs (XPath 1.0 in this case) and trying to understand why the code does what it does. Write down the obervations, new ideas, things you would have done differently, etc. Maybe, just for learning, also add a piece of self-invented syntax to the XPath machinery, in order to get a feeling how to change/extend things without breaking them. 5) I think one will need to create a scenario for oneself, where one actually _needs_ to implement XPath 2.0/XQuery 1.0/XSLT 2.0. This can either be the fact that you already told all your girl-friends that you're gonna do it (this might be not enough a reason), some idealistic reasons, some business-related issues, etc. 6) Wear heavy chains for about 2 weeks, then buy some t-shirts with XPath 2.0/XQuery 1.0/XSLT 2.0 written on it in fancy letters. 7) Try to annoy people with questions, bugzilla-entries, etc. See http://www.xmlsoft.org/bugs.html =20 But I don't know how to actually start writing such new code. Daniel will have to tell us (or at least me) what he expects; I would need to know to what extent new code for XPath 2.0 can be written and what existing code should be rather extended; so questions like: - Should the existing expression-parsing code be extended (is this possible?), or should we write on new one for XPath 2.0? - What about the XPath objects? Extend or create new code & API for XPath 2.0 objects? Finally, I think that there's no need not know much about XML-related technology to be able to code much stuff for e.g. the XPath 2.0 module. Knowledge in writing parsers and compilers should be of more help; or just the will to dig into this until it works fine.

One could consider Bison combined with a hand written tokenizer(that's how Patternist do it). Here's an XQuery grammar; path expressions and (some) XML literals are missing, but other than that it's quite complete: http://websvn.kde.org/trunk/kdenonbeta/kdom/patternist/parser/QueryTransformParser.ypp?rev=557332&view=log The tokenizer is in the same dir, but I doubt it would be useful.

It was that for me. And is..

And you can construct documents piecemeal, element, by element, and so on. So you have full control over the resulting document. Sample code depends on what language you prefer. Google for lxml and select the codespeak URL, lots of examples there, if you like Python. -- Jeroen Ruigrok van der Werven / asmodai ã€ã§ã«ãŒã³ ã©ãŠãããã¯ ãŽã¡ã³ ãã« ãŠã§ã«ãŽã§ã³ http://www.in-nomine.org/ One who knows that enough is enough will always have enough...
