xmlstarlet

问题 I have a piece of XML like so: <root> <foo src=""/> <foo src="bar"/> <foo /> </root> I want to know which elements have a src attribute , which are empty and which have values. The furthest I have come is with $ xmlstarlet sel -t -m '//foo' -v @src -n foo.xml bar Though that doesn't tell me the third foo is missing the attribute. 回答1: This will select the foos with no src attribute. /root/foo[not(@src)] For the other two tasks, I would use a mix of the expressions pointed out by @TOUDIdel and

问题 I am trying to extract the value of the 'Value' node, where the 'Key' node is 'state' within a bash shell: <FrontendStatus xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0" serializerVersion="1.1"> <script/> <State> <String> ... ... </String> <String> ... ... </String> <String> <Key>state</Key> <Value>WatchingLiveTV</Value> </String> <String> <Key>studiolevels</Key> <Value>1</Value> </String> <String> ... ... </String> <String> ... ... </String> </State> </FrontendStatus> I

问题 The command $ xmlstarlet sel -t -c "/collection/record" file.xml seems to load the whole file into memory, before applying the given Xpath expression. This is not usable for large XML files.

The example from my question could be written like this: $ xmlcutty -path /collection

问题 When running like this $ xmlstarlet sel -t -v '//department[@id="123879"]/user/@name' -n file.xml it returns only the first user's name T:106603 and an empty line.
