How do I update a string attribute with xmlstarlet

问题:

$ xmlstarlet edit -L -u "/parse-plugins/mimeType/plugin[@id='parse-html']/@id" -v 'parse-tika' conf/parse-plugins.xml

Why doesn't it replace the plugin id of mimetpes currently using parse-html plugin?

From xmlstarlet documentation:

Update value of an attribute

xml ed -u ’/xml/table/rec[@id=3]/@id’ -v 5 xml/tab-obj.xml

I'm working on nutch parse-plugins.xml.

as Mark pointed out, it works! To check that things changed use

$ xmlstarlet sel -t -c "/parse-plugins/mimeType/plugin[@id='parse-html']" conf/parse-plugins.xml

or the last-modified file attribute.
