python - XPath string as input -


considering code example below,

if 'xpath' in request.args:     in = request.args['xpath']     xml = bytesio(open("/file.xml").read())     v, e in etree.iterparse(xml):          return e.text

the following xml file,

<a>    <c>       <d>content x</d>    </c>    <c>       <d>content y</d>    </c> </a>

and in variable receives string /a/c[2]/d curl, bellow

curl http://localhost:5000/home?xpath=/a/c[2]/d

is there way given string (xpath expression) code returns element text (i.e. able understand element i'm referring to)?

to return element located in, can call find method on parsed elementtree.

return etree.parse(xml).find(in).text

note xpath expression must not include root element itself, nor starting slash, c[2]/d should trick.
