Xpath queries

[sairam132033]

Hello

I am able to write some python code, including functions. Thanks for the help

I want to write xPath Queries using Python. I need to analyze large set of xml files.

Can someone please guide me where to start or some samples?

Thanks

You can find packages here: https://pypi.python.org/pypi?%3Aaction=s...mit=search
many will come with example code, or you may find some applications which use a particular package here: http://nullege.com/

Take a look a this tutorial.
So there use BS and lxml,both work fine for parse xml.
No is it html parsing in tutorial,but not so much difference for xml.

For using xPath is lxml a good choice.
Example:

from lxml import etree

# Simulate xml
xml = '''\
<bookstore>
  <book category="web">
    <title lang="en">XQuery Kick Start</title>
    <author>James McGovern</author>
    <author>Per Bothner</author>
    <author>Kurt Cagle</author>
    <author>James Linn</author>
    <author>Vaidyanathan Nagarajan</author>
    <year>20013</year>
    <price>49.99</price>
    <year>2015</year>
    <price>30</price>
  </book>
</bookstore>
'''

tree = etree.XML(xml)

Test parse with xPath:

>>> x_path = tree.xpath("//title[@lang='en']")
>>> x_path[0].text
'XQuery Kick Start'

>>> x_path = tree.xpath("/bookstore/book[1]/year")
>>> x_path[0].text
'20013'
>>> x_path[1].text
'2015'

>>> x_path = tree.xpath(".//price")
>>> [float(i.text) for i in x_path]
[49.99, 30.0]
