Re: [lxml] How to use result of nsmap in xpath

Kun JIN schrieb am 30.09.2014 um 10:07:

"nsmap" is an lxml.element function to get namespaces of the element, usually, a None type will be returned, like:

{'olac': 'http://www.language-archives.org/OLAC/1.1/', None: 'http://www.imsglobal.org/xsd/imscp_v1p1%27%7D

i want use this namespaces in XPath, but i got an error: TypeError: empty namespace prefix is not supported in XPath

so, i must delete this NoneType by creating a new dictionay in Python:

dic_ns = {} for element in root.nsmap: if element is None: continue dic_ns[element] = root.nsmap[element]

QUESTION: is there some other methods to do this?

And the one that follows.
