Regular Expression Question

Question

This is the string that I am trying to manipulate using Regex in c#.

string hyperlinkPattern = "For more information go to <myHyperlink id = "ABC" number ="1234" someval ="11"> Hello Click here </myHyperlink>"

I am trying to get the output in following format -

For more information go to <a href = Jscript("ABC","1234","11")  Hello Click here </a>

So, I should first get the value of "id", "number" and "alt" tag from the "myHyperlink" tag and then use these value while replacing that tag with "<a href" tag. 

The input value is in string format even though it looks like html value. 

I am trying to do this using regular expression and not able to proceed with getting the pattern. Any help or clue would be highly appreciated. 

thank you
