This expressions counts all the b children whose string-value of the first text child is contained in the string-value of the child new. Well, in your case that means: is the string "
 " (text()) contained in the empty string (new)? (because b has no children of type new). This condition is false for all bs, the result should be 0. Or - different interpretation - you're using msxml, which strips whitespace-only text nodes, i.e. text() evaluates to the empty string. In this case the condition is always true, the result should be 4. > where as the below one does not give the correct value > <xsl:value-of select="count(c[contains(new,d)])"/> Well, the result is 0, and this is definitivly correct, because a has no c children at all. It has c descendants. > what is wrong in my statement > sorry for the ignorance cause i am new to xslt stuff If you could verbally explain what do you want to count then maybe someone will provide an XPath for you.
