Hi,
Sorry if this is not the right forum for this question.
If a node is bad I’m trying to comment it out. If it’s really bad
I’m trynig to delete it.
The way I’m trying to do is is as follows.
def this_is_a_problem
doc = Hpricot( html )
doc.traverse_element do |node|
if some_bad_node_test
unless really_bad?
node.swap( “” )
else
node.swap( “” )
end
end
doc.to_html
end
However I’m getting a nasty error.
TypeError: no implicit conversion from nil to integer
/usr/local/lib/ruby/gems/1.8/gems/hpricot-0.5/lib/hpricot/traverse.rb:395:in
`[]=’
Am I doing this the wrong way?
Thanx
Daniel
I can’t comment on the error, but you can delete a given node in your
traverse_element block by doing node.parent.children.delete(node).
Alternatively, you can run a search first to remove the “really bad
elements.” If you define really bad elements in terms of an xpath
query, this becomes very simple:
(doc/“script”).remove
Then you can go through and swap things out as necessary:
(doc/“xpath to bad nodes”).each do |el|
el.inner_html = “”
end

Sweet, that looks like a good way to go. I’ll try that out.
I’ve actually got it working but it’s very very slow, hopefully this
will speed it up
Thankyou
