1. A method for facilitating rule-based content mining to extract content from structured or unstructured data, the method comprising: receiving a file which contains structured or unstructured data, or a mixture of both; mining text content of the file to automatically recognize a component in the received file; converting the recognized component of the received file into semantic data, wherein the semantic data indicates one or more attributes for the recognized component; generating a processable extensible markup language (pXML) file, wherein a respective pXML element of the pXML file includes the semantic data associated with the recognized component; extracting content from the pXML file based on one or more map objects, wherein a respective map object specifies an input rule for analysis and/or output rule for formatting, wherein the respective map object further specifies one or more sub-map objects and/or sub-rules, and wherein the respective map object comprises one or more of: a map object name; a plug-and-play switch; an activation switch; and an activation order; and generating a semantic XML file corresponding to the received file and/or the extracted content based on one or more specified output rules, wherein generating the semantic XML file based on the specified output rules involves applying an XLST file or an external program and generating an application-specific XML file.
