Re: finding ancestor elements related to specific change

in reply to finding ancestor elements related to specific change

I'd strongly suggest dropping XML::Simple and using a DOM-based XML library. These tend to have useful methods called things like parentNode.

use XML::LibXML 1.70;

my $xml = XML::LibXML->load_xml(string => <<'END');
   <classes name="Panoply::BAR">
     <public_methods>
       <members name="BAR" const="no" kind="function" protection="publ
+ic" static="no" virtualness="non_virtual" volatile="no">
         <parameters declaration_name="pciReg" type="Register::Ptr" />
       </members>
       <members name="bits" const="no" kind="function" protection="pub
+lic" static="no" type="void" virtualness="non_virtual" volatile="no">
         <parameters declaration_name="value" type="uint64_t" />
       </members>
       <members name="subBitVector" const="no" kind="function" protect
+ion="public" static="no" type="void" virtualness="non_virtual" volati
+le="no">
         <parameters declaration_name="value" type="const BitVector &a
+mp;" />
       </members>
     </public_methods>
     <enums>
       <members name="ObjectState" kind="enum" protection="public" sta
+tic="no" virtualness="non_virtual">
         <values name="NEW">
         </values>
         <values name="REFRESHED">
         </values>
         <values name="DIRTY">
         </values>
       </members>
     </enums>
   </classes>
END

my @results = $xml->findnodes('//*[@declaration_name="value"]');
foreach my $result (@results) {
    print "Got result, with parent: ", $result->parentNode->getAttribu
+te('name'), "\n";
}
