Basic Usage


After installation is complete, you can start xmlsh by simply typing "xmlsh". This will run xmlsh in interactive mode.
You can use xmlsh prety much like the unix shell(s). You will be prompted with a "$"

To run a xmlsh script pass the script filename as the first argument followed by the script arguments.
C:\p4dell\DEI\xmlsh\test>xmlsh run_tests.xsh
running tests in core
Running test core_andor.xsh
Running test core_args.xsh
Running test core_brace.xsh
Running test core_case.xsh
Running test core_for.xsh
Running test core_here.xsh
Running test core_if.xsh
Running test core_subshell.xsh
Running test core_vars.xsh
Running test core_while.xsh
running tests in builtin
Running test builtin_read.xsh

Basic Syntax

xmlsh accepts the same core syntax as sh. Statements such as for, while, do, case are fully implemented.
Similarly pipelines to either internal or external commands.
For example:
$ for var in a b c ; do 
echo $var

Just as sh, the PATH variable specifies the directories
to search for external commands so right 'out of the box' you can run commands the same was as with sh.
For example, assuming "ls" and "grep" exist in your path the following works as expected

ls | grep foo


xmlsh supports both string and XML variables. See Variables for more details.
Variable types are dynamic, they take on the type of the last assigned expression.

String Variables

xmlsh supports simple string variables and variable substitution like sh.

$ V1="string"
$ V2="another $V1"
$ echo $V2
another string  

XML Variables

xmlsh also supports XML expressions and variables. See XML Expressions for details on XML Expressions.

This example creates an XML variable "x" and assigns it am xml sequence
$ x=<[1,"hi",<foo>bar</foo>,4]>
$ for a in $x ; do
echo $a
1 hi <foo>bar</foo> 4

Operating System Calls

In Linux or Windows command shells, you run commands at the prompt. E.g. to execute a Java program, run a C program
or anything else. From within an xmlsh script you can do just the same. Assume you have a Java program, in XXX.jar
that you want to run and collect the output.
op=$(java -jar XXX.jar -i inputFile.txt -t 10)

That runs the program, returns the output of the program and stores it in the $op variable ready for further use.
In this way, anything you can do from the command line you can do from within an xmlsh script
