Comma separation - xslt

Question

I have a set of productids like (123565,589655,45585,666669,5888) I want to put comma in front and back of these set of ids Like(,123565,589655,45585,666669,5888,)..
How can i write the XSLT code for doing this?

Answer 1

Just use:
<xsl:text>,</xsl:text><xsl:value-of select="$yourSequence"
separator=","/><xsl:text>,</xsl:text>

Answer 2

Depends terribly on your input XML file and what you want the output to look like. In any case, since you're using XSLT 2.0, you can use the string-join() function.
Let's say you have an input XML file that looks like this:
<products>
<product>
<name>Product #1</name>
<id>123565</id>
</product>
<product>
<name>Product #1</name>
<id>589655</id>
</product>
<product>
<name>Product #1</name>
<id>45585</id>
</product>
</products>
You could have a stylesheet like this:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:output method="text" indent="yes"/>
<xsl:variable name="SEPARATOR" select="','"/>
<xsl:template match="/">
<!--
Join the values of each products/product/id element with $SEPARATOR; prepend
and append the resulting string with commas.
-->
<xsl:value-of
select="concat($SEPARATOR, string-join((products/product/id),
$SEPARATOR), $SEPARATOR)"/>
</xsl:template>
</xsl:stylesheet>
Which would produce the following output:
,123565,589655,45585,
If you edit your question to include your input XML and what you want your output XML to look like, I can modify my answer accordingly.
