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

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

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    lt  xml version  1 0  encoding  UTF-8  standalone  yes   gt   lt root gt       lt singleElement gt           lt subElementX gt XYZ lt  subElementX gt       lt  singleElement gt       lt repeatingElement id  11  name  Joe   gt       lt repeatingElement id  12  name  Mary   gt   lt  root gt    prints   Processing repElem    Attribute id   11 Attribute name   Joe Processing repElem    Attribute id   12 Attribute name   Mary

find all   returns list of all found elements  so  input tag   soup find all attrs   quot name quot     quot stainfo quot     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   quot name quot    quot stainfo quot    output   input tag  value

I am using this with Beautifulsoup 4 8 1 to get the value of all class attributes of  certain elements   from bs4 import BeautifulSoup  html     lt td class  val1   gt  lt td col  1   gt  lt td class  val2    gt    bsoup   BeautifulSoup html   html parser    for td in bsoup find all  td        if td has attr  class            print td  class   0     Its important to note that the attribute key retrieves a list even when the attribute has only a single value
