CDATA sections are for telling an XML parser that the text inside them is not
to be interpreted as markup. There's no difference between these:
<![CDATA[foo & bar]]>
foo & bar
Both mean the string of character data "foo & bar", and this is what the XML
parser reports to the XSLT processor, and is what ends up in the text node or
attribute node in the XPath/XSLT trees. When these trees are serialized as
HTML or XML, "&" and "<" are escaped automatically in order to prevent them
from being misinterpreted as markup.
Don't worry about the input. An XSLT processor, when using the html output
method, is supposed to leave the content of a <script> element unescaped. If
your XSLT processor is not doing that, tell us which one it is and report a
bug to the vendor. Seems to work for me:
cdata.xml
=========
<data>document.write('<p>foo & bar</p>');</data>
cdata.xsl
=========
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" indent="yes" encoding="iso-8859-1"/>
<xsl:template match="/">
<html>
<head>
<title>test</title>
</head>
<body>
<h1>test</h1>
<script type="text/javascript">
<xsl:value-of select="data"/>
</script>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
result of running with 4 different XSLT processors
