In your xsl source: 
>         <card id="{$v1}" title"{$v2}">
should be <card id="{$v1} title="{$v2}">

>             <img src="<xsl:value-of select="imgsrc"/>" 
should be <img src="{imgsrc}"

> alt="<xsl:value-of
> select="imgalt"/>"/>
should be alt="{imgalt}"/>

>             <a href="<xsl:value-of select="linkhref"/>"><xsl:value-of
> select="linktitle"/></a>
should be a href="{linkhref}{linktitle}" 
Or something similar if I missed your meaning.
