xmllint unknown option '--xpath'

Question

I\'ve seen this syntax several places (eg, here):

xmllint --xpath \'/plist/array/string/text()\' tmp.xml, used to query a particular XML node using an x

Answer 1

xmllint --shell tmp.xml <<<'xpath /plist/array/string/text()'

If you need to make xmllint to read stdin:

cat /tmp/tmp.xml | xmllint --shell <(cat) <<<'xpath /plist/array/string/text()'
