Mechanism to strip specific tags from an XHTML document (but keep their contents)?
I would like a brief and easy way to strip tags from an XHTML document, and believe there has to be something curt enough among all the options like: XSLT, XPath, XQuery, custom C# programming using the .NET XML namespace. I'm open to others.
For example, I want to strip all
<b>tags from an XHTML document but keep their inner content and child tags (i.e. not simply skip the bold tag and its children).
I need to开发者_开发技巧 maintain the structure of the original document minus the stripped tags.
Thoughts:
I've seen XSLT's ability to match elements for selection; however I want to match everything by default with a couple of exceptions, and I'm unsure it's conducive to this. This is what I'm looking at right now.
XQuery I haven't started to look into. (Update for XQuery: Took a brief look at this technology and it's comparable enough to SQL in function that I fail to see how it can maintain the nested node structure of the original document - I think this is not a contender).
A custom C#/.NET XML namespace program might be viable as I already have an idea for it, but my immediate assumption is it's likely more involved contrasted with the reasons for which these other XML-specific matching languages were created.
... another kind of enabling technology I haven't yet considered...

Have you thought of XSLT? This is the language specifically designed for transforming XML and generally tree structures.
This transformation:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="b">
<xsl:apply-templates/>
</xsl:template>
</xsl:stylesheet>
when applied on any XHTML document, as the one below:
<html>
<head/>
<body>
<p> Hello, <b>World</b>!</p>
</body>
</html>
produces the wanted, correct result, in this case:
<html>
<head/>
<body>
<p> Hello, World!</p>
</body>
</html>
