This library provides a Ruby interface to Nmap's scan data. It can run Nmap and parse its XML output directly from the scan, parse a file containing the XML data from a separate scan, parse a String of XML data from a scan, or parse XML data from an object via its read() method. This information is presented in an easy-to-use and intuitive fashion for storage and manipulation.
Note that while Anthony Persaud's Perl Nmap::Parser was certainly an inspiration when designing this library, there are a number of distinguishing characteristics. Very briefly, this library contains more classes, many more methods, and has blocks extensively available.
