在lxml中重写ElementTree代码 [英] rewrite ElementTree code in lxml

问题描述

我正在编写一个代码，使用ElementTree从xml文件中提取文本，但是我发现lxml具有xpath功能，这更加方便.所以我想知道如何在lxml

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:

目前，我建议使用它.

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

希望我的问题很清楚！

推荐答案

我假设您已经处在准备使用xpath的阶段.如果没有， http://lxml.de/parsing.html 应该会有所帮助. 在第一行中用于查找元素的xpath看起来应该像这样:

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)]"

但是我不得不承认我不知道你的第二个片段应该如何找到该元素O_o

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