I would like to create a link in XSLT, my problem is I have not figured out how to include variables in the link address. For Example:

<a href="test.php?city=<xsl:value-of select="City"/>">test</a>

Try using curly braces:

<a href="test.php?city={$City}">test</a>

...sam

or you can use xsl:element and xsl:attribute, like this:
<xsl:element name="a">
  <xsl:attribute name="href">test.php?city=<xsl:value-of select="City"/></xsl:attribute>
  test
</xsl:element>

I have tried both methods but I'm not getting a well formed file because my link is actually like this test.php?city={$City}&state={$State}

It appears that the second = sign creates a problem.
Any help is appreciated.
Thank you

Try escaping the & before state:

<a href="test.php?city={$City}&amp;state={$State}">te st</a>

...sam

Now it is well formed but I still get errors. Now I get;
href="http://www.mapquest.com/maps/map.adp?city={$City}&amp;state={$State}"

highlighted with the error "Invalid variable referenceError in XPath expression, Invalid variable reference"

Any ideas?

Thank you

There is no need for a dollar sign unless City is an xsl:variable. If it's just an XPath expression use without the dollar.

As usual, I think Joe hit it on the nose. Are "City" and "State" in the XML file you are transforming, or are you creating variables within your stylesheet with names "City" and "State"?

For example, I get the following output with my examples below:

<a href="test.php?city=VarCity&amp;state=VarState">Va rTest</a>
<a href="test.php?city=XPathCity&amp;state=XPathSate" >XPathTest</a>

Example XML:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE test [
    <!ELEMENT test (#PCDATA | City | State)*>
    <!ELEMENT City (#PCDATA)>
    <!ELEMENT State (#PCDATA)>
]>
<test>
    <City>XPathCity</City>
    <State>XPathSate</State>
</test>

Example XSL (I use saxon):

<xsl:stylesheet version="1.1" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:saxon="http://icl.com/saxon">

    <xsl:output method="html"/>

    <xsl:variable name="City" select="'VarCity'"/>
    <xsl:variable name="State" select="'VarState'"/>

    <xsl:template match="test">

        <a href="test.php?city={$City}&amp;state={$State}">Va rTest</a>
        <a href="test.php?city={City}&amp;state={State}">XPat hTest</a>

    </xsl:template>

</xsl:stylesheet>

Hope that helps,
