I am trying to make an HREF tag with multiple querystring parameters using XML and XSL. Here's what I've got, but its not working: <a><xsl:attribute name="href">addcontact.asp?ID=<xsl:value-of select="//Partner/@ID" />&PartnerName=<xsl:value-of select="//Partner/@Name" /></xsl:attribute>Add Contact</a> I'm missing something obvious, I'm sure. There's got to be an easy way to do this. If I remove the second xsl:value-of statement, I get the HREF with one parameter just fine. Adding the second hoses it. Any ideas?
