1. A content management computing device, comprising: a memory; and a processor operatively coupled to the memory, the processor configured to perform the steps comprising: providing an unstructured XML file based on an unstructured document; extracting a heading, a quoted text, a text of a table of contents, and a form and table from the unstructured XML file; determining a complexity level of the unstructured XML file based on the extracted heading, quoted text, text of the table of contents, and form and table from the unstructured XML file; generating a plurality of applicable and configurable transformation rules for the unstructured XML file based on the complexity level; transforming the unstructured XML file to a structured XML file based on the plurality of applicable and configurable transformation rules and a predefined set of target schema; and validating the structured XML file against the plurality of applicable and configurable transformation rules to report incorrect transformation in the structured XML file, wherein the validating comprises identifying dropped content and repeated content from the unstructured XML to the transformed structured XML file, creating a list of defective mapping between the unstructured XML file and the structured XML file, and identifying a hierarchy mismatch between the unstructured XML file and the structured XML file.
