Python如何从xml文本节点中去除空格

Python如何从xml文本节点中去除空格

使用，

lxml

您可以遍历所有元素并检查其是否包含以下文字

strip()

：

from lxml import etreetree = etree.parse('xmlfile')root = tree.getroot()for elem in root.iter('*'):    if elem.text is not None:        elem.text = elem.text.strip()print(etree.tostring(root))

它产生：

<Person><name>My Name</name><Address>My Address</Address></Person>

---

更新 也剥离

tail

文本：

from lxml import etreetree = etree.parse('xmlfile')root = tree.getroot()for elem in root.iter('*'):    if elem.text is not None:        elem.text = elem.text.strip()    if elem.tail is not None:        elem.tail = elem.tail.strip()print(etree.tostring(root, encoding="utf-8", xml_declaration=True))
