Question

How do I insert an attribute using BeautifulSoup?

For example, insert border="1" as a <table> tag attribute.

EDIT:

I’ve answered my own question (for a particular class of table, even):

inTopic = urllib2.urlopen("file:///C:/test/test.html")
content = BeautifulSoup(inTopic)

tlist = content.findAll('table', "myTableClass")
for tbl in tlist:
    tbl['border'] = "1"
    print tbl.attrs

Answer 1

How about:

inTopic = urllib2.urlopen('http://stackoverflow.com/questions/4951331/how-do-i-insert-an-attribute-using-beautifulsoup')
content = BeautifulSoup.BeautifulSoup(inTopic)
tlist = content.findAll('table')
for tbl in tlist:
    tbl.attrs.append(('border', 1))

Do not forget to try lxml.html, it’s fast and parse well.
