How to execute XPath one-liners from shell?

by

You should try these tools :

  • xmlstarlet : can edit, select, transform… Not installed by default, xpath1
  • xmllint : often installed by default with libxml2-utils, xpath1 (check my wrapper to have --xpath switch on very old releases and newlines delimited output (v < 2.9.9)
  • xpath : installed via perl’s module XML::XPath, xpath1
  • xml_grep : installed via perl’s module XML::Twig, xpath1 (limited xpath usage)
  • xidel: xpath3
  • saxon-lint : my own project, wrapper over @Michael Kay’s Saxon-HE Java library, xpath3

xmllint comes with libxml2-utils (can be used as interactive shell with the --shell switch)

xmlstarlet is xmlstarlet.

xpath comes with perl’s module XML::Xpath

xml_grep comes with perl’s module XML::Twig

xidel is xidel

saxon-lint using SaxonHE 9.6 ,XPath 3.x (+retro compatibility)

Ex :

xmllint --xpath '//element/@attribute' file.xml
xmlstarlet sel -t -v "//element/@attribute" file.xml
xpath -q -e '//element/@attribute' file.xml
xidel -se '//element/@attribute' file.xml
saxon-lint --xpath '//element/@attribute' file.xml
