我正在使用来自 dailymed.nlm.nih.gov 的 xml 标签。在阅读与药物相关的禁忌症时，我遇到了问题。我想要标签内的所有内容，但是一旦我点击内部标签，它就会中断。我试过迭代所有子元素，但我能做的最好的就是让“警告”显示出来。“；无尿；对……过敏”丢失了。如果有人知道使用解析器获取这些数据的方法，那将有很大帮助。谢谢！

假设您正在使用类似以下内容的内容，您需要使用ET.tostring它来获取子元素的所有文本。

import xml.etree.ElementTree as ET
txt = """
<component>
<section ID="LINK_8e9e0719-efa5-451c-bea3-d547298ad0a1">
    <id root="8e9e0719-efa5-451c-bea3-d547298ad0a1"/>
    <code code="34070-3" codeSystem="2.16.840.1.113883.6.1" displayName="CONTRAINDICATIONS SECTION"/
    <title>CONTRAINDICATIONS</title>

    </text>

root = ET.fromstring(txt)

for e in root.iter('text'):
    print ">>"
    print ET.tostring(e, method="text")
    print "<<"

给

>>
