You seem to be confused about the data model. Your title mentions "nodes",
but your message mentions "tags"; you seem to be in a state where you
half-know that the input is represented as a tree but you're still mentally
behaving as if it's all a single string in which elements are represented by
textual markup.
You haven't really said what $test-text is, but my guess is that it's an
element node with three children, namely a text node containing
http://dominio.com/, an element node named b whose content is pippo, and a
text node whose content is /pluto.html. When you apply substring-before() to
an element node, it converts the first argument to a string, which is done
by taking the string-value of the element node. This is the concatenation of
all the text node descendants, namely "http://dominio.com/pippo/pluto.html";.
So you lose the hierarchic structure of the input (or, as you put it, the
"tags").
If you want to process the text while retaining the structure of the tree,
then flattening the structure into a string isn't going to help. You need to
process each text node individually. Of course, some things are going to be
very difficult to achieve, like highlighting the string "com/pip" which
straddles two nodes. Your first task is to specify what you want the output
to be in such cases.

Subject: [xsl] substring-before doesn't copy node
Hi,
I'm writing a recursive template and I have some problems
with subtring-before.
I'm trying to write a words highlighter.
In my template if my text contains the word I'm looking for, I write:
<xsl:variable name="before"
select="substring-before($test-text, .)" /> <xsl:variable
name="after" select="substring-after($test-text, .)"/>
<xsl:variable name="real-before" select="substring($text, 1,
string-length($before))"/> <xsl:variable name="real-after"
select="substring($text,
string-length($before) + string-length(.) + 1)"/>
The problem is that my test-text contains for example
http://dominio.com/<b>pippo</b>/pluto.html and
I'm looking for pluto, the before string is
http://dominio.com/pippo/. It seems that substring-before
deletes my tag <b></b>. I suppose that the problem is in the
substring-after too.
I tried to write:
<xsl:variable name="before"><xsl:copy-of
select="substring-before($test-text, .)" /></xsl:variable>
but the problem remains.
How could I solve my problem?
Best regards
Marco
