只是返回xpath中的元素文本(python/lxml) [英] Just returning the text of elements in xpath (python / lxml)

问题描述

我有一个像这样的XML结构:

I have an XML structure like this:

mytree = """
<path>
    <to>
        <nodes>
            <info>1</info>
            <info>2</info>
            <info>3</info>
        </nodes>
    </to>
</path>
"""

我目前在python lxml中使用xpath来获取节点:

I'm currently using xpath in python lxml to grab the nodes:

>>> from lxml import etree   
>>> info = etree.XML(mytree)   
>>> print info.xpath("/path/to/nodes/info")
[<Element info at 0x15af620>, <Element info at 0x15af940>, <Element info at 0x15af850>]  
>>> for x in info.xpath("/path/to/nodes/info"):
            print x.text

这很棒，但是有没有一种更干净的方法来将 just 内部文本作为列表，而不必随后编写for循环?
像这样:

This is great, but is there a cleaner way to grab just the internal texts as a list, rather than having to write the for-loop afterwards?
Something like:

print info.xpath("/path/to/nodes/info/text")

(但这不起作用)

推荐答案

您可以使用:

print info.xpath("/path/to/nodes/info/text()")
