<card id="{$v1}" title"{$v2}">

you are missing an = after title
also you don't need the variables at all, you could just do

        <card id="{cardid}" title="{cardtitle}">

  <img src="<xsl:value-of select="imgsrc"/>" alt="<xsl:value-of
   select="imgalt"/>"/>

That isn't well formed XML either: you can't have a < in an attribute
value. Use {} not xsl:value-of.
