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
