Re: Counting nodes
Gilles, >I'd like to know if it possible to count the not empty <cell> node using >xslt >eg to have a result like this: Just a bit of terminology confusion - an 'empty' element is usually one that doesn't have any content, i.e. doesn't have anything between its start and end tags, or, as in your case, has a single empty-element tag like: <cell type="start" name="Case0" pos="0"/> To count how many nodes there are of a certain type, then you should use the count() function with the argument being the nodes that you want to count. You want to select all the 'cell' elements for which a certain condition is true (they have some attributes). Where you want to select nodes that fulfil a certain condition, you should use a predicate (a boolean expression within s). So, to select all cells in your example that have some attributes, use: /board/row/cell[@*] and to count them use: count(/board/row/cell[@*]) and to display the result use: <xsl:value-of select="count(/board/row/cell[@*])" /> One thing that may or may not be an issue in your case is that if you give a DTD for your source XML, then any attributes that have a default value defined within the DTD will count as attributes within your elements. So for example if you had a DTD given as: <!DOCTYPE board [ <!ATTLIST cell type (start|bp|qcm|luck) 'qcm' name CDATA 'Case0' pos CDATA '1'> ]> then the above would not work, and in fact it would be impossible to tell which of your 'cell' elements actually had attributes defined within the XML source and which just had defaulted values from the DTD.
