Embed a hyperlink into data view web part XSLT

URL: 

http://[server]/[site]/Lists/Open%20Positions/AllItems.aspx?View={84EEA2F5-121B-40B7-946F-0FA704A1DAA1}&FilterField1=Recruiter&FilterValue1=Hold

Convert it into:
http://www.blogger.com/Lists/Open%20Positions/AllItems.aspx?View=%7b84EEA2F5-121B-40B7-946F-%200FA704A1DAA1%7d&FilterField1=Recruiter&FilterValue1=Hold

I have manually transformed the first argument from: 

{84EEA2F5-121B-40B7-946F-0FA704A1DAA1}

to: 

%7b84EEA2F5-121B-40B7-946F-0FA704A1DAA1%7d 

(In this, the open brace transforms to %7b and the closing brace transforms to %7d)
