Rip through XML files in a Directory with XPATH query with XMLStarlet

dirxpath.sh

## DirXPath
## --------
## 
## Requirements:
## =============
## Ensure that XMLStarlet is installed on your machine (http://xmlstar.sourceforge.net/)
##
## Install
## =======
## Put the following in your .bashrc (Linux/Unix/Cygwin/MinGW) or .bash_profile (Mac) file. Then source the file.
##
## ```
## source ~/.bashrc
## ```
##
## Usage
## =====
## Syntax: dirxpath <option: -v / -c> <xpath>
##
## If you want only values in the node, run:
## ```
## dirxpath -v //vs:GivenName
## ```
## 
## If you want a dump of the XML node that corresponds to your 
## xpath query, run:
## ```
## dirxpath -c //vs:GivenName
## ```
## 
## NOTE: My default namespace is "vs", and so I needed to replace 
## it with "_" to work with xmlstarlet. You can remove this entirely.
## To do so, look remove this line: new_xpath=${orig_xpath//vs/_}
## and replace all instances of $new_xpath with $old_xpath.
