XSLT2 - Get text of all nodes except certain ones
Question
I'm trying to get the text of a whole HTML looking document but I would like to exclude certain nodes from the retrieval.
XML
<body>
<p>some text</p>
<p>some text <img src="whatever"><alt>alt title</alt></p>
<div>
<p>some text</p>
</div>
</body>
Context
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xsl:template match="/">
<html>
<body>
<table>
<xsl:for-each select="collection(...)">
<xsl:variable name="text" select="string(//body)" />
<tr>
<td><xsl:value-of select="$text"/></td>
</tr>
</xsl:for-each>
<table>
</body>
</html>
</xsl:template>
</stylesheet>
Expected result
I want everything but the alt element so some text *3 = 29 in this example.
I am doing this operation from a for-each on a collection of file. So right now I just do a string(/body) to get everything in each of my file.
I was thinking of a recursive call:
<xsl:function name="lp:gettext">
<xsl:param name="n" />
<xsl:choose>
<xsl:when test="$n/child::node()">
<xsl:value-of select="concat(text(),lp:gettext($n/child::node()))" />
</xsl:when>
<xsl:when test="$n/name()='alt'" />
<xsl:otherwise>
<xsl:value-of select="text()" />
</xsl:otherwise>
</xsl:choose>
</xsl:function>
But I can't seem to use child:: in a function it seems, or not like I do.
How can I achieve what I want to do?

Applying the following stylesheet:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="alt"/>
</xsl:stylesheet>
to your input (after closing the img tag!) returns:
<?xml version="1.0" encoding="UTF-8"?>
some textsome text some text
This is because the built-in template rules copy all text nodes to the output - so all you need to do is override the default behaviour for the nodes you don't want to be copied.
Added:
Based on the stylesheet you have added to your question, I believe the following should do what you want (I cannot test it):
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:strip-space elements="*"/>
<xsl:template match="/">
<html>
<body>
<table>
<tr>
<td>
<xsl:apply-templates select="collection(...)"/>
</td>
</tr>
<table>
</body>
</html>
</xsl:template>
<xsl:template match="alt"/>
</xsl:stylesheet>

好的，我只是发现了这个remove-elements-deep函数，似乎完全可以实现我想要的功能。
