Hi All,
I am facing some problem in retaining the HTML tags during XSL
transformation.
Given below are the details.
May I summarize that as follows? The input is the output with
replaced by <br /> elements and the whole content inside two quotes
(with some elements stripped, but not their content)?
Hi Ambika,
Since you appear to do text node matching, I thought to try something
new (well, in XSLT 2.0 it is not so new, but I haven't seen it myself
before in XSLT 1).
I call it "stringized template matching" (where you can apply template
rules for ordinary strings from substring-before() etc.), to prevent
complex recursive call-template calls. It is very easy to implement and
it is applicable to almost all replace-string situations. There's one
drawback: it only works with the extension function fn:node-set().
However, there are only few processors that have not implemented it for
XSLT 1. But there's also a big advantage: it becomes tremendously easier
to read.
I know, I know, it was not your problem: you already have your
replace-string function in place (replacing newlines with <br>). But, if
I am right about your question (confirm, please), you can solve it very
simply by using the following solution (creates your requested output).
I took the liberty to add an additional rule for removing
whitespace-only nodes. Not sure you want that.
It is easy enough to add matches for replacing double quotes, too. If it
gets more complex, I advice to use modes for the more generic matches,
so as to not make it too complex.
Happy coding!

On the following XML:
<elem id="11" date="10 Jan 2007" time="16:55">
Non Title
<title>Title Here</title>
<text>
<p>without newline</p>
<PRE> (Start of pre tag)
<p>
Within P
</p>
After P tag
(End of pre tag)
</PRE>
</text>
</elem>
It creates (second line one line):
Elem id, New details
11,"<br>Non Title<br><title>Title Here</title><p>without
newline</p><PRE>(Start of pre tag)<br><p><br>Within P<br></p><br>After P
tag<br>(End of pre tag)<br></PRE>"
Here's the XSLT that does it all:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:exslt="http://exslt.org/common";
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="text" indent="yes"/>
<xsl:template match="/">
<xsl:text>Elem id, New details </xsl:text>
<xsl:apply-templates />
</xsl:template>
<xsl:template match="elem">
<xsl:value-of select="@id"/>
<xsl:text>,"</xsl:text>
<xsl:apply-templates select="node()" />
<xsl:text>" </xsl:text>
</xsl:template>
<!-- general rule: keep these nodes -->
<xsl:template match="*">
<xsl:value-of select="concat('<', name(), '>')"/>
<xsl:apply-templates select="node()" />
<xsl:value-of select="concat('</', name(), '>')"/>
</xsl:template>
<!-- specific rule: 'throw away' these nodes, but keep content -->
<xsl:template match="text">
<xsl:apply-templates select="node()" />
</xsl:template>
<!-- throws away whitespace only text nodes -->
<xsl:template match="text()[normalize-space(.) = '']" />
<!-- matches text nodes with newline -->
<xsl:template match="text()[contains(.,
' ')][not(normalize-space(.) = '')]">
<xsl:variable name="before">
<xsl:value-of select="substring-before(., ' ')" />
</xsl:variable>
<xsl:variable name="after">
<xsl:value-of select="substring-after(., ' ')" />
</xsl:variable>
<xsl:apply-templates select="exslt:node-set($before)/node()" />
<xsl:text><br></xsl:text>
<xsl:apply-templates select="exslt:node-set($after)/node()" />
</xsl:template>
<!-- matches text nodes without newline -->
<xsl:template match="text()[not(contains(., ' '))]">
<xsl:value-of select="normalize-space(.)"/>
</xsl:template>
