OPML Utils

OPML? According to http://dev.opml.org/

OPML an XML-based format that allows exchange of outline-structured information between applications running on different operating systems and environments.

OPML files are used as a way to export (and import) subscriptions in feed reader applications.

Those XSLT files have been tested with xslproc but should work with any XSLT 1.0 processor. Given you have an OPML file called feeds.opml, here is how to use them.

Convert an OPML file to an HTML page

convert-to-html.xsl is able to convert the OPML file to an HTML5 document.

xslproc convert-to-html.xsl feeds.opml

Convert an OPML file to an HTML fragment

convert-to-html-fragment.xsl does pretty much the same of convert-to-html.xsl except that it omits the html, head and body elements.

xslproc convert-to-html-fragment.xsl feeds.opml

Filter feeds from a category

filter.xsl allows you to filter feeds from a category to produce another OPML file. Feeds from sub-categories are also included. This stylesheet expects the name of the category in parameter.

xsltproc --stringparam text "My category" filter.xsl feeds.opml
