Description:
------------
XSLT processor occasionally generates improper result with the XML and XSL data inputted. Even worse, it happens with out any sign or regular operation, which means I can't reproduce this bug. With the same XML + XSL, it gives a perfect result sometimes, but occationally, a buggy result.

The reproduce code is just an idea of what's happening, cuz the actual code I'm running is way too long to submit here. Please ask for it if you could identify this as a BUG, and I'll submit further info.

Reproduce code:
---------------
XML:
...
<root>
  <a>1</a>
  <b>2</b>
</root>
...
XSL:
...
<script type="text/javascript">
<for-each select="/root/*">
  SomeHash.set('<xsl:value-of select="name()" />', <xsl:value-of
select="." />);
</for-each>
</script>
...

Expected result:
----------------
<script type="text/javascript">
  SomeHash.set('a', 1);
  SomeHash.set('b', 2);
</script>

Actual result:
--------------
The result could be such a mass SOMETIMES:
<script type="text/javascript">
  SomeHash.set('a', 1b2;
</script>

It would help both you and us if you provided an actual working reproduce script.  It would help you catch obvious mistakes like the fact that you forgot the xsl namespace on the for-each tags there.

I wrote a script to see if I could reproduce your problem:

<?php
$xml = <<<EOB
<root>
  <a>1</a>
  <b>2</b>
</root>
EOB;
$xsl = <<<EOB
<xsl:stylesheet version="1.0" 
              xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                  xmlns="http://www.w3.org/TR/xhtml1/strict">
<xsl:template match="/">
<script type="text/javascript">
<xsl:for-each select="/root/*">
  SomeHash.set('<xsl:value-of select="name()" />', <xsl:value-of select="." />);
</xsl:for-each>
</script>
</xsl:template>
</xsl:stylesheet>
EOB;
$x = DOMDocument::loadXML($xml);

$xslt = new XSLTProcessor();
$s = new DOMDocument();
$s->loadXML($xsl, LIBXML_NOCDATA);
$xslt->importStylesheet($s);
echo $xslt->transformToXML($x); 

And the output of this script for me is:

<?xml version="1.0"?>
<script xmlns="http://www.w3.org/TR/xhtml1/strict" type="text/javascript">
  SomeHash.set('a', 1);

  SomeHash.set('b', 2);
</script>

which seems correct.  Can you verify that you get the same output?
