[xsl] writing to a file in xslt

[a kusa <akusa8@xxxxxxxxx>]

Hi

I have a requirement where I am reading from a file and assigning
values in the XSL style sheet. But when I read the values form this
external file, I have to compare it with what got assigned before this
and if it is the same, I have to increment this new value.

So for example, I have a folder with 5 XML files. When I am processing
the first XML file, I go read the external text file and grab the
first value and assign it to this first XML file.
Now, when processing the second XML file, I again go to grab the next
value from the external file, but this time I have to compare this
value with what was assigned to XML file number 1, and if they are the
same, I have to increment this value by 1 before assigning it to the
second XML file.

So is there any way to write to another file in XSLT? If I can do
that, then maybe I can compare the next value by reading that new
file.

Well,  I am not able to figure out the best approach for this problem.

Can the experts please guide me here?

Thanks in advance.
