User:Jeblad/XMLstarlet

XMLstarlet adds a tag and parser functions to make it possible to hot link data from external sources by extracting data from web services or published xml or html documents. Such services are assumed to be services for national statistics and other services for distinct and systematic data, but also highly complex and structured data.

Usage
The extension relies upon redirection through system messages for access to external sites, or cooperation from the external site. The file code>robots.txt is checked to see if the extension is allowed to use the specified content from the external site if there are no redirect through the system messages. If access are allowed the extension will download and make a local cached version for further use.
