I am attempting to parse, not evaluate, rails ERB files in a Hpricot/Nokogiri type manner. The files I am attempting to parse contain HTML fragments intermixed with dynamic content generated using ERB (standard rails view files) I am looking for a library that will not only parse the surrounding content, much the way that Hpricot or Nokogiri will but will also treat the ERB symbols, <%, <%= etc, as though they were html/xml tags.
Ideally I would get back a DOM like structure where the <%, <%= etc symbols would be included as their own node types.
I know that it is possible to hack something together using regular expressions but I was looking for something a bit more reliable as I am developing a
tool that I need to run on a very large view code base where both the html content and the erb content are important.
For example, content such as:
blah blah blah
<divMy Great Text <%= my_dynamic_expression %</div
Would return a tree structure like:
root
- text_node (blah blah blah)
- element (div)
- text_node (My Great Text )
- erb_node (<%=)
