XSL attributes

in my xslt, i create one html anchor (<a>...</a>) for evry match of "folder" in the xml.

i need to create one more anchor to be adjusent to the first anchor (i.e. (<a>...</a><a>...</a>) for the same match of "folder".

to do so, i've added the second entry of the new anchor to the xslt, just after the closing of the first anchor (in the same matching "folder" rule).

i'm gettign an "xsl attribute should not start with characters '<'" error when running it.

What am i doning wrong and how to fix it?
