You must have Perl 5.8.0 or later. Windows users may use Cygwin or ActivePerl from ActiveState.

XSH also requires several extra Perl modules, especially XML::LibXML (>= 1.62), Parse::RecDescent, and Term::ReadLine::Perl. All required modules are bundled in a package available in the Download Section.

If you prefer to install the required modules individually, e.g. from CPAN, here is a complete list:

• libxml2
• Term-ReadLine-Perl
• Text-Balanced
• Parse-RecDescent
• Text-Iconv
• XML-NamespaceSupport
• XML-SAX-Base
• XML-SAX
• XML-NodeFilter
• XML-Filter-BufferText
• XML-LibXML-Common
• XML-LibXML (>= 1.62)
• XML-LibXML-Iterator
• XML-LibXSLT
• XML-SAX-Writer
• XML-XUpdate-LibXML
• XML-Filter-DOMFilter
