Hi,
In my html I have a bunch of code like this:
<html><body><script>a="<a href='teste'>";</script></body></html>
If I parse this with BS4 I get what is the correct (in the strict
sense) result:
>>> from bs4 import BeautifulSoup
>>> from bs4 import CData
>>> html = "<html><body><script>a=\"<a href='teste'>\";</script></body></html>"
>>> s = BeautifulSoup(html)
>>> s
<html><body><script>a="<a href='teste'>";</script></body></html>
But even though it's correct it does not work in the browser because
now the browser thinks the variable a is "<a href='teste'>".
Weird but true.
I'd like to get the code wrapped in a cdata, so I did this:
>>> script_text = s.html.body.script.children.next()
>>> cdata = CData(script_text.string)
>>> cdata
u'a="<a href=\'teste\'>";'
>>> script_text.replace_with(cdata)
>>> s
<html><body><script><![CDATA[a="<a href='teste'>";]]></script></
body></html>
Is this the correct behavior? Shouldn't it be?:
<html><body><script><![CDATA[a="<a href='teste'>";]]></script></body></
html>
If not, how can I achieve this? I now that doing:
>>> s.encode(formatter=None)
'<html><body><script><![CDATA[a="<a href=\'teste\'>";]]></script></
body></html>'
Works, but I'd like it to still correct wrong chars inside an <a> tag,
for example and using formatter=None would not correct those, so....
Any help is appreciated.
Cheers,
Gustavo
