XSLT - Get String between commas - xslt

Question

How can I get the value 'four' in XSLT?
<root>
<entry>(one,two,three,four,five,six)</entry>
</root>
Thanks in advance.

Answer 1

You didn't specify the XSLT version, so I assume version 2.0.
I also assume that word four is only a "marker", stating from which place
take the result string (between the 3rd and 4th comma).
To get the fragment you want, you can:
Use tokenize function to "cut" the whole content of entry
into pieces, using a comma as the cutting pattern.
Take the fourth element of the result array.
This expression can be used e.g. in a template matching entry.
So the example script can look like below:
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:transform version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" encoding="UTF-8" indent="yes" />
<xsl:template match="entry">
<xsl:copy>
<xsl:value-of select="tokenize(., ',')[4]"/>
</xsl:copy>
</xsl:template>
<xsl:template match="#*|node()">
<xsl:copy><xsl:apply-templates select="#*|node()"/></xsl:copy>
</xsl:template>
</xsl:transform>
For your input XML it gives:
<?xml version="1.0" encoding="UTF-8"?>
<root>
<entry>four</entry>
</root>
