How to determine if a element exists #37

Closed clviper closed 7 years ago

clviper commented 7 years ago

Hi there. I noticed that there was already two issues regarding this topic (#27 and #28) but they were closed without any additional information.

Is there any implemented method to do that? I did not noticed that in the source code.

Currently I have a ugly workaround implemented that is to convert the element to str and then use .find() to determine if the target element exists.

Thank you. And good work with untangle.

Hello @clviper ,

there's no straightforward way to do that right now, so a workaround is the only way to go. Maybe using dir to get a list is somewhat more elegant, even if not more efficient:

>>> x = untangle.parse('<doc><node-with-title><title>test</title></node-with-title><node-no-title></node-no-title></doc>')
>>> dir(x.doc.node_with_title)
[u'title']
>>> dir(x.doc.node_no_title)
[]
>>> 'title' in dir(x.doc.node_with_title)
True
>>> 'title' in dir(x.doc.node_no_title)
False

I hope this helps! And thank you for the compliment 👍
