RE: Incrementing a variable in XSL

read this before you post next time.

from that you would have found

xsl variables are not what you think they are.  They can't be modified.  This does what you described.

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="2003-1-16-1500.xslt"?>
<docroot>
	<a>1</a>
	<a>2</a>
	<a>3</a>
	<a>4</a>
</docroot>

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="docroot">
        <root>
            <xsl:for-each select="a">
	    <position><xsl:value-of select="position()"/><original value="{.}"/></position>
	</xsl:for-each>
        </root>
    </xsl:template>
</xsl:stylesheet>

Subject:  Incrementing a variable in XSL


Hello ,
I have a simple XML file as below:
<?xml version="1.0" encoding="UTF-8"?>
<docroot>
  <a>1</a>
  <a>2</a>
  <a>3</a>
  <a>4</a>
</docroot>

I have written a XSL stylesheet as below:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="docroot">
    <xsl:variable name="var">1</xsl:variable>
    <xsl:for-each select="a">
       <xsl:value-of select="$var"/>  
       <!-- incrementing $var ?? --> 
    </xsl:for-each>    
</xsl:template>
</xsl:stylesheet>

I want to increment a variable in <xsl:for-each ..,
and print it with <xsl:value-of ..

There is a situation where in the XML file, a tag
repeats and I want to output the no's 1, 2, 3 etc in
the output with each tag instance.

How can I do this?

Regards,
Mukul
