don't need regular expression. just do a split on amazon

>>> s="""lksjdfls <div id =\'amazon_345343\'> kdjff lsdfs </div> sdjfls <div id =   "amazon_35343433">sdfsd</div><div id=\'amazon_8898\'>welcome</div>"""

>>> for item in s.split("amazon_")[1:]:
...   print item
...
345343'> kdjff lsdfs </div> sdjfls <div id =   "
35343433">sdfsd</div><div id='
8898'>welcome</div>

then find  ' or " indices and do index  slicing.
