The code you posted is _full_ of microsoft- wd-xsl spcifuc syntax  that
won't work with an xslt processor.

> Even though I change the namespace, it doesn't work.
If you are using msxml2, then it knows nothing of xslt, so an xslt
stylesheet obviously won't work, but the solution is to use a system
that isn't so old, not to write in wd-xsl.

just to point out the main places you need to change.

> <xsl:stylesheet xmlns:xsl="http://www.w3.org/TR/WD-xsl">

wrong namespace, missing version attribute.

       <xsl:if match=".[matrix=1]">

xsl:if does not have a match attribute
[ can not be used after .


Once those are fixed so you have xslt then probably you need to change

<xsl:value-of select="topic/detail/tableheading1" />

to

<xsl:value-of select="tableheading1" />

as the current element is already the detail element because of the 
       <xsl:for-each select="topic/detail">
