xml - 跟踪 XML 子项

Question

我想一次跟踪一个按钮元素。但不仅仅是按钮的内容。

我想去追踪:

 <BUTTON XY="100,300" TOMAP="SECOND" WARLEVEL="02_deamon" REQUIRE="03_cityMonsters" UNTIL="04_chaosBlaBla">Description1...</BUTTON>

但是，我知道按钮确实包含数据，因为它跟踪 REQUIRE。问题只是跟踪部分。它要么像 map.toString() 那样跟踪太多，要么像 button.toString() 那样跟踪太少。

在闪存中:

...
var map:XML = world.MAP[_map];

trace(map.toString());

做我想做的，痕迹:

<MAP NAME="FIRST">
     <BUTTON XY="100,300" TOMAP="SECOND" WARLEVEL="02_deamon" REQUIRE="03_cityMonsters" UNTIL="04_chaosBlaBla">Description1...</BUTTON>
     <BUTTON XY="100,400" TOMAP="FIRST" WARLEVEL="03_cityMonsters" REQUIRE="03_cityMonsters" UNTIL="04_chaosBlaBla">Description2...</BUTTON>
     <BUTTON XY="200,300" TOMAP="PREBOSS">GO-TO STUFF</BUTTON>
     <BG>backgrounds/firstBg.jpg</BG>
</MAP>

但是

for (var i = 0; i < map.BUTTON.length(); i++) {

    var button:XML = map.BUTTON[i];
    if (button.@REQUIRE != undefined) {
        trace("found REQUIRE ");  // Traces: found REQUIRE 
    }
    trace(button.toString());

}

没有做我想做的事，痕迹:

Description1...

XML 文件:

<WORLD>
  <MAP NAME="FIRST">
    <BUTTON XY="100,300" TOMAP="SECOND" WARLEVEL="02_deamon" REQUIRE="03_cityMonsters" UNTIL="04_chaosBlaBla" >Description1...</BUTTON>
    <BUTTON XY="100,400" TOMAP="FIRST"  WARLEVEL="03_cityMonsters"  REQUIRE="03_cityMonsters" UNTIL="04_chaosBlaBla" >Description2...</BUTTON>
    <BUTTON XY="200,300" TOMAP="PREBOSS" >GO-TO STUFF</BUTTON>

    <BG>backgrounds/firstBg.jpg</BG>
  </MAP>
  <MAP NAME="SECOND">
    <BUTTON XY="100,300" TOMAP="FIRST"  WARLEVEL="03_cityMonsters"  REQUIRE="03_cityMonsters" UNTIL="04_chaosBlaBla" >Description3...</BUTTON>
    <BUTTON XY="100,250" TOMAP="SECOND" >Description4..</BUTTON>
    <BG>backgrounds/firstBg.jpg</BG>
  </MAP>
</WORLD>

尝试toXMLString()

trace(button.toXMLString());
