bash - XPath to list available tags non recursively (using xmllint in a shell script) -

i'm trying build xpath argument utilize in programme xmllint (used within bash shell script) homecoming list of available tags within tag (while not listing subtags).

here's sort of xml have:

<functioninformation> <class> setup </class> <description> natural language description of function. </description> <prerequisitefunctions> myfunction1 myfunction2 </prerequisitefunctions> <prerequisiteprograms> myprogram1 myprogram2 </prerequisiteprograms> </functioninformation>

this xml stored in bash variable functioninformation.

the output have when using xmllint on xml following:

class description prerequisitefunctions prerequisiteprograms

i should note tags returned in non recursive way (i not want available tags or subtags listed).

i can access info in tags using xmllint in way such following:

descriptionfunctioninformation="$(echo "${functioninformation}"\ | xmllint --xpath '/functioninformation/description/text()' -\ | xargs -i echo -n "{}")"

could point me in right direction on how may build xpath (or similar) homecoming info need?

you can utilize xmlstarlet:

xmlstarlet sel -t -m '/*/*' -v 'concat(name(.)," ")' < xmlfile

bash list xpath tags
