dojox.html.format.prettyPrint removes html5 custom-data attributes

[Ferdinand Weinberger]

    var tag = '<div data-dojo-type="dijit.form.Button" data-dojo-props="label: \'myButton\'" id="testbutton" data-dojo-id="myButton" style="border: 1px solid black;"></div>';
    
    //will result <div id="testbutton" style="border: 1px solid black;"> </div>
    console.log(dojox.html.format.prettyPrint(tag));

the problem is the regular expression to find attributes in the html-string.

dojox/html/format.js line 38

var rgxp_attrsMatch = /\s\w+=("[^"]*"|'[^']*'|\S*)/gi;

should be changed to

var rgxp_attrsMatch = /[\w-]+=("[^"]*"|'[^']*'|\S*)/gi;
