xsl:variable

Hi Friends,
I stuck into a problem, could any body suggest me how can we assign the value to a global variable in the template or it's not allowed in xsl.I am trying...

<xsl:variable name="out" select="$l+1"/>

here out is global variable which i declared above the template & "l" is a local variable.

Thanks
Gunjan

<?xml version='1.0'?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xslutput method="html" indent="no" encoding="utf-8"/>
<xsl:variable name="in" select="1000"/>
<xsl:template match="/">
<xsl:variable name="out" expr="$in + 1"/>
<xsl:value-of select="$out"/>
</xsl:template>

</xsl:stylesheet>

Thanks niha for the reply what exactly i am trying to do is like that

<?xml version='1.0'?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xslutput method="html" indent="no" encoding="utf-8"/>
<xsl:variable name="out" select="1000"/>
<xsl:template match="/">
<xsl:variable name="in" select="6"/>

<!-- Now i want to manipulate the value of "out" so i can use it for diffrent purpose in the template -->

<xsl:variable name="out" expr="$in +1"/>
</xsl:template>

</xsl:stylesheet>


Hope now you can understand

Thanks

<xsl:value-of select="$out"/>

<xsl:value-of select="$out+1"/>

Is it possible in XSL that we assign the value to a global variable & later in the template we modify it's value.

Thanks

hi
according to XSLT Programmers reference Michael Kays book
" unlike variables in many programming languages, XSLT variables can not be updated. Once they are given a innitial value, they retain that value until they go out of scope" (pg no:: 336)

in ur case global variable means its scope is in entire that program so you can not updated it - this is whats my opinion anyway...if anyone out there got another theory would like to hear

hope this info helps

Thanx niha that's what i just want to confirm.

Hello,

Small tip.
Usually you can use template calls or even recursive calls instead changing variable value. So use template parameter instead variable.
