Some Tutorial might help you getting behind RegExp. Some RegExp Tester might help you testing your regular expressions.

aside from that, you're probably looking for

var string = "http://www.somewhere.com/0123456789.html",
    id = string.match(/\/(\d+)\.html/)[1];
alert(id);

This should do it.

var string = "http://www.somewhere.com/0123456789.html";
string.replace(/^.*\/(.*)\.html$/, "$1");

var path = document.location.path;
var id = path.replace('.html', '');

Simply:

var str = "http://www.somewhere.com/0123456789.html";  
var result = /\d+/.exec(str);

Result:

0123456789
