E.g.,I have following variables:  
myInput, DataFile,TagFile in the following segment HTML codes.

```
Select Asn1 File: 
    Select Asn1-bas File:
```

If in PHP, I can easily get them by $p\_DataFile, $p\_TagFile etc, How can  
I get the variables in embeded ruby?

Thanks

Select Asn1 File: 
     Select Asn1-bas File:

just a note, but i don’t think you want the ‘form’ action to go to the  
file itself (the rhtml) … it should go to the corresponding action that  
calls that template.

i believe what you are seeking for is params[:DataFile],  
params[:TagFile], etc.  
(this may be good for the ruby on rails forum, rather than this plain  
ruby forum) [http://www.ruby-forum.com/forum/3](http://www.ruby-forum.com/forum/3)

anyway hth.  
happy sunday

OP didn’t say Rails. Could very well be serving some kind of eruby.

You probably want to use the CGI class:  
[http://ruby-doc.org/core/classes/CGI.html](http://ruby-doc.org/core/classes/CGI.html)

That page has plenty of tutorials on it, but the basics are:

require ‘cgi’  
cgi = CGI.new  
data\_file = cgi[‘DataFile’]

That’ll give you the value of the DataFile text field.

Isn’t hpricot ([http://redhanded.hobix.com/inspect/hpricot01.html](http://redhanded.hobix.com/inspect/hpricot01.html)) an  
html parser package?
