How to solve following problem?

Indexing: write a Python script "index.py" that take an "input" directory with a collection of XML documents, then output an index file also in XML format. The index should contain for each token, the token's value, and all of this token's provenance. 'which' tag should include the name of the XML file that has the token, and "where' tag should include the path to find the token in relevant file. You can assume values are tokenized by white spaces and punctuation characters. For example: yarn.nodemanager.aux-services' can be tokenized to ['yarn', 'nodemanager', 'aux', 'services"]. (You don't need to consider about numbers like '1.0'.) Execution format: Python index.py input index.xml Example of output file: yarn mapred-site. xml configuration. property . value capacity-scheduler. xml configuration. property . name capacity-scheduler. xml configuration . property . value yarn-site. xml configuration. property . name >
