Extract javascript variable value from html document with python
I need to parse an HTML document that contains javascript code with json object.
Something lik开发者_高级运维e this:
<html>
<head>
</head>
<body>
<script type="text/javascript">
myJSONObject = {"name": "steve", "city": "new york"}
</script>
<p>Hello World.</p>
</body>
</html>
How can I extract the myJSONObject value with python?
You can use lxml to parse the HTML, and then extract the JSON:
>>> import lxml.etree,json
>>> s = '''<html><body><script type="text/javascript">
myJSONObject = {"name": "steve", "city": "new york"}
</script></body></html>'''
>>> js = lxml.etree.HTML(s).find('.//body/script').text
>>> jsonCode = js.partition('=')[2].strip()
>>> json.loads(jsonCode)
{u'city': u'new york', u'name': u'steve'}
加载中,请稍侯......
