Hi Charles,

I need to extract the first 5 children from an element.
I used the following syntax and I have problems with it.

Do I need to escape the condition ( position()&lt;4 ).

Well yes, if this XPath is to be used in XSLT (which it is). For XSLT to parse it must be well-formed XML, which includes escaping magic characters in attribute values.

But there's also a difference between the first five elements, and the first five elements of a given type ('element' elements, for example): you might want simply

/*/*[position() &lt;= 5]

to get the first five children of the document element, whatever their names are.
