Need to xpath xml data based on greater than date attribute. The dashes in the date below prevent the greater than symbol from working. Is there a way to remove the dashes in the xml on the fly?
XML
<revisions>
<revision date="2010-07-12">blah</revision>
<revision date="2010-06-12">blah</revision>
</revisions>
PHP
$rdate = 2010-07-01;
$programs = $item->xpath("/programs/program[revisions/revision[@date>'".$rdate."']]");
You might try:
Edit: one should note that in XPath 2.0 the
compare()function is available (-1 smaller, 0 equal, 1 higher), so you can just compare strings. As far is I know most PHP implementations are still using XPath 1.0 though.
