How to find/replace text in html while preserving html tags/structure
我想搜索并替换HTML文本。我不想摆弄标签或标签的属性,而只是HTML文本。我应该如何在Python中做到这一点?
最佳答案
import lxml.etree as et
html=\
"""
<!DOCTYPE html>
<html>
<head>
<title>Hello HTML</title>
</head>
<body>
<p>Hello 1</p>
<p>Hello 2</p>
<p>Hello 3</p>
<p>Hello 4</p>
</body>
</html>
"""
doc = et.fromstring(html)
for i in doc.xpath('.//p[contains(.,"Hello") and not(contains(.,"4"))]'):
i.text='replaced'
print et.tostring(doc,pretty_print=True)
出:
<html>
<head>
<title>Hello HTML</title>
</head>
<body>
<p>replaced</p>
<p>replaced</p>
<p>replaced</p>
<p>Hello 4</p>
</body>
</html>
