[XML-SIG] Parse MULTIPLE XML files in a directory

[amitesh kumar]

Hi,

Please review the following code and help me.

Here I'm trying to :
1. Read each XML file in a folder.
2. Parse file.
3. Store some of the tags values as key-value pair in a map
4. Similarly maintain another collection that'll store one list per file.
