    Getting elements and text with lxml

    Hello,

    I have an XML file that starts with:

    <vortaro>
    <art mrk="$Id: a.xml,v 1.10 2007/09/11 16:30:20 revo Exp $">
    <kap>
    <ofc>*</ofc>-<rad>a</rad>
    </kap>

    out of it, I'd like to extract something like (I'm just showing one
    structure, any structure as long as all data is there is fine):

    [("ofc", "*"), "-", ("rad", "a")]

    How can I do it? I managed to get the content of boths tags and the
    text up to the first tag ("\n "), but not the - (and in other XML
    files, there's more text outside the elements).

    Thanks.

      Look for the "tail" attribute.

          That gives me the last part, but not the one in the middle:

          In : etree.tounicode (e)
          Out: u'<kap>\n <ofc>*</ofc>-<rad>a</rad>\n</kap>\n'

          In : e.text
          Out: '\n '

          In : e.tail
          Out: '\n'

          Thanks.

              You need the text content of your initial element's children, which
              needs that of their children, and so on.

                  or maybe this is enough:

                  list(root.itert ext())

                      Hello,

                      My object doesn't have iter() or itertext(), it only has:
                      iterancestors, iterchildren, iterdescendants , itersiblings.

                      Thanks.
