Retrieval of Structure and Content Information from XML Document
Most of the time data over internet is not found in structured and it's also not flexible to store and parse it using databases. XML is used to represent huge amount of data without any absolute schema and structure. To retrieve information from XML document two techniques are used keyword search and query retrieval. Keyword search is used when the authors have to match exact word and it does not support for exact answer. Query retrieval is used whenever document is following certain schema but its availability of documents with schema is partially fulfilled.
