Quick XPath question (REXML)

Rails
1

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

elements in the
document):

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

shouldn’t just_rows contain all of the

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

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}
