Folks,
We have got some strange behavior while dealing with XSP pages containing
a lot of nested/scoped xml:lang attributes as well as XML-Namaspaces
(which are not used for taglibs but simply to differentiate tags into the
XSLT space).
foo.xml:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet href="foo.xsl" type="text/xsl" ?>
<page version="1.0" xml:lang="en" xhtml="http://www.w3.org/1999/xhtml";>
<pagetitle xml:lang="en">English</pagetitle>
<sourceLanguage>en</sourceLanguage>
<sentence>
<key xml:lang="en">key1</key><value xml:lang="en">test
in English</value>
</sentence>
</page>
is processed fine; and yields (full output a the end of this message):
.. cut..
<body>
<h1>test in English</h1>
</body>
.. cut..
when (full xsl at the end of this msg):
<xsl:template match="*" mode="body">
<body>
<h1><xsl:value-of select="//sentence[key='key1']/[EMAIL
PROTECTED]:lang='en']" disable-output-escaping="yes"/></h1>
</body>
is applied but this XSP:
<?xml version="1.0" encoding="UTF-8" ?>
<?xml-stylesheet href="NULL" type="application/x-xsp" ?>
<?xml-stylesheet href="foo.xsl" type="text/xsl" ?>
<xsp:page
xmlns:xsp="http://apache.org/xsp/core/v1";
xmlns:param="http://axkit.org/NS/xsp/param/v1";
>
<page version="1.0" xml:lang="en"
xmlns:xhtml="http://www.w3.org/1999/xhtml"; >
<pagetitle xml:lang="en">English</pagetitle>
<sourceLanguage>en</sourceLanguage>
<sentence>
<key xml:lang="en">key1</key><value xml:lang="en">test
in English</value>
</sentence>
</page>
</xsp:page>
(page .. /page byte by byte the same as in the xml file) yields:
<body>
<h1></h1>
</body>
without the key value. Using AxTraceIntermediate we can see xml:lang
beeing preserved (see end of file for those internediate files).
We find that things do work if we
- remove any xmlns:foo namespace we define
- put the tags in a flat namespace (we're NOT using taglibs)
- and do an overall 's/xml:lang/lang/g'
To us it looks like a bug into the AxKit XML NS processing code and/or in
relation to xml:lang (is that very special to AxKit?) - it seems there is
a mention something about it into TODO of 1.62 though. Any immediate hint
or patch to apply ? (We tried on FreeeBSD and MacOSX).
Any pointers or suggestions as how to solve this ?
