Is there a built in function/plugin that converts  
relative paths from a html page to absolute ones?

Example:  
target url: [http://mysite.com/folder/url.html](http://mysite.com/folder/url.html)

url content:  
…

some link  
…

converted content:  
…

\< a href=“[http://mysite.com/folder/link.html](http://mysite.com/folder/link.html)”\>some link\</ a\>  
…

How can I accomplish this using ruby ?

Dear Ciocan,

you could use something like

str=“[http://mysite.com/folder/url.html](http://mysite.com/folder/url.html)”  
p File.dirname(str)  
p File.basename(str)  
p File.basename(str,“.html”)

Best regards,

Axel

Use URI#merge:
