Changing href atributes with nokogiri and ruby on rails

- by fool

Hi, I Have a HTML document with links links, for exemple: <html> <body> <ul> <li><a href="http://someurl.com/etc/etc">teste1</a></li> <li><a href="http://someurl.com/etc/etc">teste2</a></li> <li><a href="http://someurl.com/etc/etc">teste3</a></li> <ul> </body> </html> I want with Ruby on Rails, with nokogiri or some other method, to have a final doc like this: <html> <body> <ul> <li><a href="http://myproxy.com/?url=http://someurl.com/etc/etc">teste1</a></li> <li><a href="http://myproxy.com/?url=http://someurl.com/etc/etc">teste2</a></li> <li><a href="http://myproxy.com/?url=http://someurl.com/etc/etc">teste3</a></li> <ul> </body> </html> What's the best strategy to achieve this?

XML Pretty Printer Missing 2 Key Edge Cases

- by viatropos

Using this xslt file found on this blog to pretty print xml using Nokogiri, everything almost works, but to the point where I can't use it for HTML. First, if a node is empty, it turns it into a self closing node, so: <textarea></textarea> gets converted to <textarea/> But that messes up the html tree when rendered. Second, if the node just has text, the text isn't tabbed, and the closing node isn't tabbed, so: <li> <label>some text</label> </li> becomes: <li> <label>some text </label> </li> ...but it would ideally be: <li> <label> some text </label> </li> Does anyone who's pro at XSLT know a quick fix for this?
