Parsley Functions

Parselets can be written in JSON, XML, or language-specific data structures in (currently) Ruby and Python.

Parselets support a combination of CSS, Xpath, and XSLT functions and selectors, as well as some built-in functions. Custom Functions are also supported.

Available functions:

• All Xpath functions, and the leading fn: is not required
• All of CSS3 selectors, except selectors that don’t make sense without a mouse, such as :hover
• Parsley functions:
  • parsley:html-document(uri) which fetches an html page from the uri, and parses it. For example: parsley:html-document("http://google.com")//title
  • parsley:nl which normalizes text containing <p>, <br>‘s, etc. into plain text. (Remember: ’nl’ stands for ‘new line’.)
• And from EXSLT:
  • date:add-duration
  • date:add
  • date:date-time
  • date:date
  • date:day-abbreviation
