尝试处理一个非常简单的 html5 脚本并使用 html5lib 渲染它
import html5lib
html = '''<!DOCTYPE html>
<html lang="en">
<head>
<title>Hi</title>
</head>
<body>
<script src="a.js"></script>
<script src="b.js"></script>
</body>
</html>
'''
parser = html5lib.HTMLParser(tree = html5lib.treebuilders.getTreeBuilder("lxml"))
walker = html5lib.treewalkers.getTreeWalker("lxml")
serializer = html5lib.serializer.htmlserializer.HTMLSerializer()
document = parser.parse(html)
stream = walker(document)
theHTML = serializer.render(stream)
print theHTML
输出如下:
<!DOCTYPE html><html lang=en><head>
<title>Hi</title>
</head>
<body>
<script src=a.js></script>
<script src=b.js></script>
是的。它只是中途切断。将树构建器从 lxml 更改为 dom 没有任何作用。调整 HTML 会改变输出，但它仍然很损坏。
最佳答案
所以关键似乎是 omit_Optional_tags=False 不知怎的，缺少它会吃掉输出的末尾。
parser = html5lib.HTMLParser(tree = html5lib.treebuilders.getTreeBuilder("lxml"))
document = parser.parse(html)
walker = html5lib.treewalkers.getTreeWalker("lxml")
stream = walker(document)
s = serializer.htmlserializer.HTMLSerializer(omit_optional_tags=False)
output_generator = s.serialize(stream)
for item in output_generator:
print item
<!DOCTYPE html>
<html lang=en>
<head>
<title>
Hi
</title>
</head>
<body>
<script src=a.js>
</script>
<script src=b.js>
</script>
</body>
</html>
