xml_attribute_ignoring_namespace.sh

#!/bin/bash

# See https://stackoverflow.com/questions/40796231/how-does-xpath-deal-with-xml-namespaces.
# To ignore namespaces use local-name(), for example:
#
# xmllint --xpath '//*[local-name()="structMap" and @TYPE="LOGICAL"]/*[local-name()="div"]/@TYPE' meta.xml 

# Working example.
cat <<EOXML | xmllint --xpath '//*[local-name()="structMap" and @TYPE="LOGICAL"]/*[local-name()="div"]/@TYPE' -
<?xml version="1.0" encoding="UTF-8"?>
