Introduction to Installing XML Parser using Shell-Bash

xml::parser is a Perl module that provides an event-based parser for XML documents. It is especially useful for parsing large XML documents, as it keeps only a small amount of the XML document in memory at any given time.

To install xml::parser using Shell-Bash, follow the steps below:

1. Open a terminal window and navigate to the directory where you want to install xml::parser.

2. Run the following command to download the installation package:

   wget https://www.cpan.org/authors/id/T/TO/TODDR/XML-Parser-2.44.tar.gz
   

3. Extract the downloaded package using the following command:

   tar -zxvf XML-Parser-2.44.tar.gz
   

4. Navigate to the extracted directory:

   cd XML-Parser-2.44
   

5. Run the following command to install xml::parser:

   perl Makefile.PL
   make
   make test
   make install
   

6. Verify that xml::parser is installed by running the following command:

   perl -e 'use XML::Parser;'
   

   If no error message is displayed, then xml::parser is installed successfully.

In summary, installing xml::parser using Shell-Bash involves downloading the installation package, extracting it, navigating to the extracted directory, and running the installation commands (i.e., Makefile.PL, make, make test, and make install). Once installed, you can verify that xml::parser is working by running a test command.
