Variable scope

[John]

I'm new to XSLT and I've been trying to figure out a solution for the
last couple of days. The XML & XSLT stylesheet are below. Basically I
want to declare some language (English, French, etc.) variables at the
beginning of the stylesheet, however I keep getting variable scope errors.

The language strings are specific to this template. There aren't many
since most of the data is coming from an application through XML. Below
is a simplified example. I'm trying to accomodate multiple languages
without having to maintain multiple stylesheets. Any ideas on how to
accomplish this?

XML:
----
<root>
<language>en</language>
</root>

XSL:
----
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xslutput method="html" encoding="UTF-8" indent="yes" />

<xsl:if test="//language = 'en'">
<xsl:variable name="language">English</xsl:variable>
</xsl:if>

<xsl:if test="//language = 'fr'">
<xsl:variable name="language">French</xsl:variable>
</xsl:if>

<xsl:template match="/">
<xsl:value-of select="$language" /> <== variable 'language' not found
</xsl:template>

</xsl:stylesheet>

Thanks!

XSL:
----
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xslutput method="html" encoding="UTF-8" indent="yes" />

<xsl:if test="//language = 'en'">
<xsl:variable name="language">English</xsl:variable>
</xsl:if>

<xsl:if test="//language = 'fr'">
<xsl:variable name="language">French</xsl:variable>
</xsl:if>

<xsl:template match="/">
<xsl:value-of select="$language" /> <== variable 'language' not found
</xsl:template>

</xsl:stylesheet>

Try this:

<xsl:variable name="language">
<xsl:if test="//language = 'en'">English</xsl:if>
<xsl:if test="//language = 'fr'">French</xsl:if>
</xsl:variable>

The XSL way of doing things takes a little bit of getting
your head round, but you'll soon get the hang of it.

Try this:

<xsl:variable name="language">
<xsl:if test="//language = 'en'">English</xsl:if>
<xsl:if test="//language = 'fr'">French</xsl:if>
</xsl:variable>

or use xsl:choose, xsl:when, xsltherwise.
