如何在python中的xml标记之间保存文本？

Question

I am trying to get the text between the xml tags. There are several posts about it, but what I don't understand is how to save it in a variable. The code below prints what I want, but as soon as I replace "print" with "return" it doesn't save this text in the variable. I think I am missing something very simple here.

from xml.sax import make_parser, handler

line = '<text><p><s id="1">Some text <someothertag>some more text</someothertag></s></p></text>'
class extract_text(handler.ContentHandler):
    def characters(self, data):
        print data.strip()

parser = make_parser()
parser.setContentHandler(extract_text())
parser.feed(line)

So I would like to have a variable, which would be equal to "Some text some more text" Any idea is very welcome!

If you just return value from the handler it will not be stored anywhere. You need to do it yourself:

result = ''

class extract_text(handler.ContentHandler):
    def characters(self, data):
        global result
        result += data.strip() + '\n'

parser = make_parser()
parser.setContentHandler(extract_text())
parser.feed(line)

print(result)
