Interacting with system commands using a web dev language

First of all, sorry for the vague title.

Let me explain. At work we're currently using SunGrid

I've been assigned a project to create a web interface wrapper for intera开发者_JAVA技巧cting with the engine. i.e. displaying users jobs, submitting jobs via a nice GUI etc. (most of the sgrid commands output xml which is nice)

My question for you chaps is the following:

What web dev language would you use to interact with the system? i.e. use the language to do a system call and evaluate the response.

I'm not after an argument on which language is best, I just would like to know which language is specifically good for interacting with the system and is also good for web dev.

almost any web oriented language could interact with system commands.

I personally would use python (you can use a framework like django, pylons etc.. or as CGI), and is great interacting with system commands and XML

In python you can do all the system calls and reponse evaluation via

• subprocess module for simple, non-interactive commands (you run a command with parameters, it does its work, returns a result and exits)
• pexpect for complex commands where you also are requested to do some input before it stops

for XML you have XML Elementtree module
