Here's an example:

<eInfoResult>
<DbList>
        <DbName>pubmed</DbName>
        <DbName>protein</DbName>
        <DbName>nucleotide</DbName>
        <DbName>nuccore</DbName>
        <DbName>nucgss</DbName>
....



>>> record['DbList'][0]       
'pubmed'
>>> record['DbList'][0].tag
u'DbName'
>>> record['DbList'][0].attributes
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'StringElement' object has no attribute 'attributes'
>>> 

So currently record['DbList'] is a list of StringElements (actually, a ListElement of StringElements) where the XML tag name is stored in a .tag attribute. If we don't store the .tag attribute, then record['DbList'] would become a list of plain strings.
