XPath

[ShakyMobo]

<line><c n="H7">Drinkin' all </c><c n="E">night</c><c n="E7">We got in to a
</c><c n="A">fight</c></line>

XPath: substring(/line/c[position()=1], 3, 7)

Is it possible to refer to the textelement that contains the value of the
substring in XSLT? In this case the firstchild of the first "c" element.
I'm doing this in Java, and my clumsy solution was to take out the string
"/line/c[position()=1]" and find the firstchild of the returned node.
I need to split up the textelement in order to insert a new element inside
the textelement, and that's why i need to point at the textelement.

I am not sure I understand, in the DOM there are different kind of
nodes, there are element nodes and there are text nodes but I don't know
what you think a textelement is.
As for XPath, surely you can do
/line/c[1]/text()[1]
to select the first text child node of the first <c> element child node
of the <line> root element.

I was probably thinking of the textnode
But the thing is that I can't change the Xpath expression
"substring(/line/c[position()=1], 3, 7)"
Is it possible to use that expression to find the textnode that contains
resulting string?

I am not sure I understand what you want to achieve, you can write
predicates in XPath expression to filter out certain nodes e.g.
/line/c/text()[contains(., substring(/line/c[position()=1], 3, 7))]
