使用Python ElementTree查找包含特定文本的“标题” xml标记的父元素 [英] Find parent element of a 'title' xml tag containing specific text using Python ElementTree

问题描述

我想解析一个xml文件并提取包含< title> < sec> >使用Python 3.7&匹配特定文本ElementTree

I wish to parse an xml file and extract the parent <sec> which contains a <title> matching a specific text using Python 3.7 & ElementTree

    ...
    <sec id="s0010">
     <label>2</label>
     <title>Materials and methods</title>
     </sec>
    <sec id="s0015">
     <label>3</label>
     <title>Summary</title>
     </sec>

     ...

我能够使用ET查找标题：

I was able to locate the title using ET:

for title in parent.iter('title'):
                        text = title.text
                        if(text):
                                if("methods" in text.lower()):
                                        print("**title: "+text+"****")

但是我如何获得该对象的父对象（< sec> ）标题是否包含感兴趣的文本？

But how do I get the parent object (<sec>) of the title containing the text of interest?

推荐答案

执行（嵌套）迭代需要2个步骤： sec ，然后点击标题。像这样的东西：

Do a (nested) iteration in 2 steps: on sec and then on title. Something like:

for sec in parent.iter("sec"):
    for title in sec.iter("title"):
        text = title.text
        if text and "methods" in text.lower():
            print("**title: " + text + " **** sec id: " + sec.get("id", ""))
