javascript - Redirecting multiple values in URL with Greasemonkey -

i'm trying greasemonkey automatically redirect page when hits url, , redirect page 2 of same values. instance:

http://www.google.com/page=438985&view=49834 into: http://www.google.com/document/page=438985/field&view=49834&done

i've tried following:

var links,thislink; links = document.evaluate("//a[@href]",     document,     null,     xpathresult.unordered_node_snapshot_type,     null);  (var i=0;i<links.snapshotlength;i++) {     var thislink = links.snapshotitem(i);      thislink.href = thislink.href.replace(regexp('http://www.google.com/page=($1)&view=($2)'),                                           'http://www.google.com/document/page=$1/field&view=$2&done'); } 

var links = document.getelementsbytagname('a'); for(var = links.length - 1; >= 0; i--) {     if(links[i] && links[i].href) {         links[i].href = links[i].href.replace(/http:\/\/www\.google\.com\/page=(\d+)&view=(\d+)/,                         'http://www.google.com/document/page=$1/field&view=$2&done');     } }
