That's what template matching is all about. For-loops are a usage from 
imperative languages, whereas XSLT more like a functional one. Using a 
template match will 'call' that template automagically each time the 
processor encounters a node that fits the specification in the 
match-attribute.

Thus, instead of using for-each, you could best use the example from 
Richard. It will save you from a lot of xsl:if and xsl:choose branches 
(also procedural heritage)

This will select ALL infoObjects, at any level, however deep and is an 
expensive operation. Better do it so:

<xsl:apply-templates 
select="infoObject/infoObjectDetail[@title='Description']" />

<xsl:template match="infoObjectDetail">
<tr>   
   <td>       
   <xsl:value-of select="."/>
   <xsl:text>&#160;</xsl:text>
   </td>
</tr>
</xsl:template>

Or like this, if you have more of this type of matches, you can specify 
it more precisely at template level:

<tr>   
   <td>       
        <xsl:apply-templates select="infoObject/infoObjectDetail" />
   </td>
</tr>

<xsl:template match="infoObjectDetail[@title='Description]">
   <xsl:value-of select="."/>
   <xsl:text>&#160;</xsl:text>
</xsl:template>

<xsl:template match="infoObjectDetail[@title!='Description]">
   NO DESCRIPTOIN FOUND!
</xsl:template>


Of course, if you insist, you can always stick to the for-each loop.
