Question

I have an HTML file like this:

 <tr>
   <td class= 'iconmenu' width="100%">...</td>
 </tr>
 <tr>
   <td class= 'iconmenu' width="100%">...</td>
   <td class= 'iconmenu'>...</td>
</tr>

The first element has one child and the second has two child, the question is:

How can I check if the first element has one child?

Answer 1

Counting the number of child elements of the first tr:

count(/*/tr[1]/*)

Counting only td children:

count(/*/tr[1]/td)

Perform the comparison like this:

<xsl:if test="count(/*/tr[1]/td)=1">

Note the use of an absolute path (starting with /). You may be tempted to do count(//tr[1]/td). Note that this returns the count of all tds across every row that is the first row in every table in the document.
