Links Regex Replace HTML with new

I'm trying to run a regex to to do this:

Replace all instances of an apk file in a document:

<a href="http://download.mydomain.com/files/androidfile.apk">

With:

<a target="_blank" href="http://mydomain.com?f=http://download.mydomain.com/files/androidfile.apk">

With this JQUERY code:

$('body').contents().filter(function() {
    return this.nodeType === 3;
}).each(function() {
    $(this).replaceWith($(this).text().replace(/<a href~/^.*\.(apk)$/i, 'http://mydomain.com?f=">$1</a>'));
});

So essentially, remove the code before download.mydomain.com/files/androidfile.apk, that is <a href="http:// and replace with <a target="_blank" href="http://mydomain.com?f=http://. There might be several of this in a page so I need a solution that might match and replace all.

The Regex and replacing doesn't seem to work, what might be a solution to this.

So in summary, I want to be able to do this in JQuery:

<html>

<a href="http://download.domain.com/files/androidfile1.apk"><img src="theme/download.gif" border=0 alt="download" height="120px" width="130px"></a><br/>

<a href="http://download.domain.com/files/androidfile2.apk"><img src="theme/download.gif" border=0 alt="download" height="120px" width="130px"></a><br/>

<a href="http://download.domain.com/files/androidfile3.apk"><img src="theme/download.gif" border=0 alt="download" height="120px" width="130px"></a><br/>

<a href="http://download.domain.com/files/androidfile4.apk"><img src="theme/download.gif" border=0 alt="download" height="120px" width="130px"></a><br/>

<a href="http://download.domain.com/files/androidfile5.apk"><img src="theme/download.gif" border=0 alt="download" height="120px" width="130px"></a><br/>

</html>

To this:

<html>

<a href="http://mydomain2.com?f=http://download.domain.com/files/androidfile1.apk"><img src="theme/download.gif" border=0 alt="download" height="120px" width="130px"></a><br/>

<a href="http://mydomain2.com?f=http://download.domain.com/files/androidfile2.apk"><img src="theme/download.gif" border=0 alt="download" height="120px" width="130px"></a><br/>

<a href="http://mydomain2.com?f=http://download.domain.com/files/androidfile3.apk"><img src="theme/download.gif" border=0 alt="download" height="120px" width="130px"></a><br/>

<a href="http://mydomain2.com?f=http://download.domain.com/files/androidfile4.apk"><img src="theme/download.gif" border=0 alt="download" height="120px" width="130px"></a><br/>

<a href="http://mydomain2.com?f=http://download.domain.com/files/androidfile5.apk"><img src="theme/download.gif" border=0 alt="download" height="120px" width="130px"></a><br/>

The code below should do the trick. Rather than use regex, I used the ends with selector. This should serve the same purpose, and execute quicker. Instead of rewriting the tag completely, I just modified the attributes using jQuery.attr(). A live example is here.

<!DOCTYPE html>
<html>

<head>
<title>test</title>
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>
<script type="text/javascript">
$(document).ready(function()
{
    $('a[href$=apk]').each(function()
    {
        var mydomain = "http://mydomain2.com?f=";
        var $this = $(this);

        $this.attr("href", mydomain+$this.attr("href"));
        $this.attr("target", "_blank");
    });
});
</script>
</head>

<body>
<a href="http://download.domain.com/files/androidfile1.apk"><img src="theme/download.gif" border=0 alt="download" height="120px" width="130px"></a><br/>
<a href="http://download.domain.com/files/androidfile2.apk"><img src="theme/download.gif" border=0 alt="download" height="120px" width="130px"></a><br/>
<a href="http://download.domain.com/files/androidfile3.apk"><img src="theme/download.gif" border=0 alt="download" height="120px" width="130px"></a><br/>
<a href="http://download.domain.com/files/androidfile4.apk"><img src="theme/download.gif" border=0 alt="download" height="120px" width="130px"></a><br/>
<a href="http://download.domain.com/files/androidfile5.apk"><img src="theme/download.gif" border=0 alt="download" height="120px" width="130px"></a><br/>

</body>
</html>

The resulting output is:

<a target="_blank" href="http://mydomain2.com?f=http://download.domain.com/files/androidfile1.apk"><img src="theme/download.gif" alt="download" height="120px" border="0" width="130px"></a><br>
<a target="_blank" href="http://mydomain2.com?f=http://download.domain.com/files/androidfile2.apk"><img src="theme/download.gif" alt="download" height="120px" border="0" width="130px"></a><br>
<a target="_blank" href="http://mydomain2.com?f=http://download.domain.com/files/androidfile3.apk"><img src="theme/download.gif" alt="download" height="120px" border="0" width="130px"></a><br>
<a target="_blank" href="http://mydomain2.com?f=http://download.domain.com/files/androidfile4.apk"><img src="theme/download.gif" alt="download" height="120px" border="0" width="130px"></a><br>
<a target="_blank" href="http://mydomain2.com?f=http://download.domain.com/files/androidfile5.apk"><img src="theme/download.gif" alt="download" height="120px" border="0" width="130px"></a><br>

What you are doing is overkill, although it won't work, why selecting all the elements on the page? if you want to select a elements why not selecting them using $('a')? For adding a string to the href attributes, you can use attr method.

$('a').filter(function() {
    return this.href.indexOf('apk')
}).attr('href', function(i, href) {
    return 'http://mydomain.com?f=' + href
}).attr('target', '_blank');
