Someone suggested me to replace linefeed characters in my text area with an
empty block <fo:block></fo:block>.
Problem is, I don't know what character to look for (xml is encoded in utf-8 on
a windows machine).
The numeric character entity 
 matches a newline, so
replace(textArea,'
[
]*','
') will replace all multiple newlines
with a single newline.
If you are constrained to using XPath 1.0, you could write a recursive named
template to do the job, testing for two newlines each time, and replacing with
one, until no double newlines are left, then emitting an <fo:block/>
