An XML document contains another XML element, which is wrapped in CDATA.
How can the wrapped XML be used for XSL and XSL-FO transformation (version 1)?
回答1:
This is not possible with standard XSLT 1.0 or 2.0, in a single transformation.
It can be done using Saxon 9 Professional Edition or Enterprise Edition. These products have a saxon:parse() extension function. Or use the XPath 3.0 parse-xml() function, which is also supported by recent versions of Saxon PE/EE.
As @grtjn points out, it is possible to do it with a two-pass process. Stylesheet 1 turns the CDATA-wrapped text into parseable XML (using <xsl:value-of select="whatever" disable-output-escaping="yes"/>). Stylesheet 2 then processes the serialized result produced by stylesheet 1.
回答2:
If you are willing to take multiple transformation steps then it is possible. Output the relevant section with disable-output-escaping to turn the escaped XML into valid XML. Process it in a subsequent step.
It does require the escaped XML to be well-formed. And some parsers require the intermediate result to be serialized (to disk or else) first to make sure the escaped XML is properly unescaped before it enters the subsequent transformations.
