Question

I am trying to write a python program that uses DOM to read xml file and print another xml structure that list from only one node with particular selected attribute “fun”.

<?xml version="1.0" encoding="ISO-8859-1"?>
<website>
    <url category="fun">
        <title>Fun world</title>
        <author>Jack</author>
        <year>2010</year>
        <price>100.00</price>
    </url>

    <url category="entertainment">
        <title>Fun world</title>
        <author>Jack</author>
        <year>2010</year>
        <price>100.00</price>
    </url>
</website>

I couldn’t select the list from the URL having category=”fun”.

I tried this code:

for n in dom.getElementsByTagName('url'):
    s = n.attribute['category'] 
    if (s.value == "fun"):
        print n.toxml()

Can you guys help to me to debug my code?

nb: One of your tags opens “Website” and attempts to close “website” – so you’ll want to fix that one…

You’ve mentioned lxml.

from lxml import etree as et

root = et.fromstring(xml)
fun = root.xpath('/Website/url[@category="fun"]')
for node in fun:
    print et.tostring(node)
