在lxml中重写ElementTree代码

Question

I am writing a code to extract text from a xml file using ElementTree but I found out that lxml is giving xpath features which is more convenient. So i want to know how this line could be rewritten in lxml

if x.nodeName == 'a:pPr' and x.getAttribute('lvl') == '2' and x.hasAttribute('marL') == False:

currently I am suggested to use this..

'/p:sld/p:cSld/p:spTree/p:sp/p:nvSpPr/p:nvPr/x[@type="body" and  @sz="quarter"  and  @marL]'

Hope my question is clear!

Answer 1

I'm assuming you are already at a stage where you're ready to use an xpath. If not http://lxml.de/parsing.html should help. The xpath for finding the element, you are searching for in your first line should look like this:

"//a:pPr[@lvl=2 and not(@marL)]"

I however have to admit that I have no idea how your second snippet should find that element O_o
