This is a live score board based on PC^2 API, and runs quite well during the onsite contest of 2012/2015 ACM-ICPC Asia Regional Changchun Site. It offered some fancy features like showing the animation of the real time changes of teams' ranking.
The code is a little old, ugly, imperfect as I am looking back now, three years later. There should have better design of the system as well as user experiences. But it still works. I do not have planty of time to improve it nowadays, but if you plan to use it, and faced problems, I would like to provide support as much as I can (You can reach me by QQ: 416529576, or email).

Firstly, download "Export empty template" in the standing tab of you site. Secondly, replace that xml file using regex expression, from .+?ReservationID="(.+?)".+?TeamName="(.+?)".+?> to "\2":"\1", Then, edit the data to json format, and you will get something like this:
var tn2id={"+18远古遗愿":"161940", "ALPC_ACOnFingers":"161713", "ALPC_Tour_de_Force":"161714",...};
Thridly, paste the the code above and the code following into Chrome javascript console, you will get the final exporting xml.
var result="";
for(var t=board.headTeam.nextTeam;t!=board.tailTeam;t=t.nextTeam){
if(t.en=="BHU_sec")t.en="BHU_Sec";
if(tn2id[t.en.xss()]==undefined){
if(t.offical)
console.log("error:"+t.en.xss());
continue;
}
result+='';
}
