Extracting an attribute value with beautifulsoup

.find_all() returns list of all found elements, so:

input_tag = soup.find_all(attrs={"name" : "stainfo"})

input_tag is a list (probably containing only one element). Depending on what you want exactly you either should do:

output = input_tag[0]['value']

or use .find() method which returns only one (first) found element:

input_tag = soup.find(attrs={"name": "stainfo"})
output = input_tag['value']

In Python 3.x, simply use get(attr_name) on your tag object that you get using find_all:

xmlData = None

with open('conf//test1.xml', 'r') as xmlFile:
    xmlData = xmlFile.read()

xmlDecoded = xmlData

xmlSoup = BeautifulSoup(xmlData, 'html.parser')

repElemList = xmlSoup.find_all('repeatingelement')

for repElem in repElemList:
    print("Processing repElem...")
    repElemID = repElem.get('id')
    repElemName = repElem.get('name')

    print("Attribute id = %s" % repElemID)
    print("Attribute name = %s" % repElemName)

against XML file conf//test1.xml that looks like:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<root>
    <singleElement>
        <subElementX>XYZ</subElementX>
    </singleElement>
    <repeatingElement id="11" name="Joe"/>
    <repeatingElement id="12" name="Mary"/>
</root>

prints:

Processing repElem...
Attribute id = 11
Attribute name = Joe
Processing repElem...
Attribute id = 12
Attribute name = Mary

If you want to retrieve multiple values of attributes from the source above, you can use findAll and a list comprehension to get everything you need:

import urllib
f = urllib.urlopen("http://58.68.130.147")
s = f.read()
f.close()

from BeautifulSoup import BeautifulStoneSoup
soup = BeautifulStoneSoup(s)

inputTags = soup.findAll(attrs={"name" : "stainfo"})
### You may be able to do findAll("input", attrs={"name" : "stainfo"})

output = [x["stainfo"] for x in inputTags]

print output
### This will print a list of the values.

I would actually suggest you a time saving way to go with this assuming that you know what kind of tags have those attributes.

suppose say a tag xyz has that attritube named "staininfo"..

full_tag = soup.findAll("xyz")

And i wan't you to understand that full_tag is a list

for each_tag in full_tag:
    staininfo_attrb_value = each_tag["staininfo"]
    print staininfo_attrb_value

Thus you can get all the attrb values of staininfo for all the tags xyz
