Python & lxml / xpath: Parsing XML

Question

I need to get the value from the FLVPath from this link : http://www.testpage.com/v2/videoConfigXmlCode.php?pg=video_29746_no_0_extsite

from lxml import html

sub_r = requests.get("http://www.testpage.co/v2/videoConfigXmlCode.php?pg=video_%s_no_0_extsite" % list[6])
sub_root = lxml.html.fromstring(sub_r.content)

for sub_data in sub_root.xpath('//PLAYER_SETTINGS[@Name="FLVPath"]/@Value'):
     print sub_data.text

But no data returned

You're using lxml.html to parse the document, which causes lxml to lowercase all element and attribute names (since that doesn't matter in html), which means you'll have to use:

sub_root.xpath('//player_settings[@name="FLVPath"]/@value')

Or as you're parsing a xml file anyway, you could use lxml.etree.

You could try

print sub_data.attrib['Value']

url = "http://www.testpage.com/v2/videoConfigXmlCode.php?pg=video_29746_no_0_extsite"
response = requests.get(url)

# Use `lxml.etree` rathern than `lxml.html`, 
# and unicode `response.text` instead of `response.content`
doc = lxml.etree.fromstring(response.text)

for path in doc.xpath('//PLAYER_SETTINGS[@Name="FLVPath"]/@Value'):
     print path
