Rails - Feb 2007 - Quick XPath question (REXML)

All,

If I have the following (assume that xml contains a valid REXML Document
and that the root of the xml is way above any <tr> elements in the
document):

just_rows = xml.elements["//tr[starts_with(@id,
''xdgDataRow_grid_container_'')]"]

shouldn''t just_rows contain _all_ of the <tr> elements whose id
attributes start_with "xdgDataRow_grid_container_"?

It''s only getting the first one.  Do I need to add something to the
XPath to pull all of the <tr> elements under the root?

Thanks,
Wes

Try :

XPath.each(doc, ''//tr etc'') do |node|
   p node
end

Maybe .elements only returns contiguous matches.

Thanks!

This seems to work well:

just_rows = ''''
REXML::XPath.each(xml, "//tr[starts_with(@id, 
''xdgDataRow_grid_container_'')]") {|node| just_rows
<< node.to_s}
