variable in xslt

[saran3b2]

hi friends

i am new user.

i am in the process of collecting the main content and number of title from the input XML with XSLT.
I have doubt in variable increament. how to increamtent variable ?

this is my xml:

<chunk-meta><title km="Pt.Ttl">PT</title></chunk-meta>
<chunk-meta><title km="At.Ttl">no need</title></chunk-meta>
<float><meta><title km="Ch.Ttl">CT</title></meta></float>
<float><meta><title km="N.Ttl">no need</title></meta></float>
<float-meta><meta><title km="H1.Ttl">HT</title></meta></float-meta>

i expect output to be like this:

<title km="Pt.Ttl">PT</title><no>1</no>
<title km="Ch.Ttl">CT</title><no>2</no>
<title km="H1.Ttl">HT</title><no>3</no>

this is my xslt:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml"/>
<xsl:template match="/">
<xsl:variable name="a" select="1"/>
<xsl:for-each select="//">
<xsl:if test="title/@km[contains(.,'Pt.T')]">
<xsl:copy-of select="title"/><no><xsl:copy-of select="$a"/></xsl:if>
<xsl:if test="title/@km[contains(.,'Ch.Ttl')]"><xsl:variable name="b" select="$a+1"/>
<xsl:copy-of select="title"/><no><xsl:copy-of select="$b"/></xsl:if>
<xsl:if test="title/@km[contains(.,'H1.Ttl')]">
<xsl:variable name="c" select="$b+1"/><xsl:copy-of select="title"/><no><xsl:copy-of select="$c"/></xsl:if>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>

thanks in adv

I would suggest seperating these particular elements out in order to make them easier to count. Then use the position function to easily get their number.
[code=xml]
<?xml version="1.0" encoding="UTF-8"?>
<xsl:styleshe et version="1.0" xmlns:xsl="http ://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format">
<xsl:template match="/">
<xsl:for-each select="//title[.!='no need']">
<xsl:copy-of select="."/>
<no><xsl:valu e-of select="positio n()"/></no>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
