Thanks Mike for your help.



Since I have no way of knowing which elements in the source xml would have 
newlines, would it mean that I will need to have the normalize-space 
function all over my xsl sheet?

XML parsers normalize CR+LF to LF, except in attribute values containing
a CR written as a numeric character reference like
. So in XSLT you
get only LFs (
) 99.999% of the time.

To better understand what is going on, you should use something that helps 
you

create a more tangible representation of the XPath/XSLT node tree.



XPath tree visualization stylesheets you can apply to the above XML:
  http://skew.org/xml/stylesheets/treeview/ascii/
  http://skew.org/xml/stylesheets/treeview/html/
  http://www.cranesoftwrights.com/resources/showtree/

Software providing XPath tree visualization:
  http://www.topxml.com/xpathvisualizer/
  http://www.logilab.org/xpathvis/
  and various XML editors like XML SPY.

In the case of the element named 'attr', its child text node will
encapsulate the text (linefeed character) + 'value' no matter what
you do, because it is considered signficant in the XPath data model.

If you don't wish to use this text verbatim, you may find that applying the
XPath function normalize-space() to the node or string will give you the
string you wanted. The normalize-space function takes the "string-value" of
its argument, strips leading and trailing whitespace, and collapses
intermediate runs of whitespace to a single space character, returning an
XPath string object.
