本文介绍了一种使用Flex将数据网格中的数据导出到XML文件的方法，并通过PHP脚本实现文件保存。具体步骤包括遍历数据网格获取数据、构造XML结构、调用PHP接口完成文件保存。

Flex 代码区

MyDataDG为datagrid,执行提交数据代码:


private var WillsavedXML:String;
		private function sendOutXML(event:MouseEvent):void
		{
			var savedXML:XML= <table></table>;

			for (var j:int=0; j < MyDataDG.dataProvider.length; j++)
			{
				var tempXML:XML=<subLeaf></subLeaf>
				for (var k:int=0; k < MyDataDG.columns.length; k++)
				{
					if (MyDataDG.dataProvider.getItemAt(j) != undefined && MyDataDG.dataProvider.getItemAt(j) != null)
					{
						if (MyDataDG.columns[k].labelFunction != undefined)
						{
							trace(Math.ceil(MyDataDG.columns[k].width))
							trace("labelFunction==" + MyDataDG.columns[k].labelFunction(MyDataDG.dataProvider.getItemAt(j), MyDataDG.columns[k].dataField))
						}
						else
						{
							//trace("width"+Math.ceil(MyDataDG.columns[k].width))
							var savedStr:String=MyDataDG.dataProvider.getItemAt(j)[MyDataDG.columns[k].dataField]
							var should:XML=new XML("<" + MyDataDG.columns[k].headerText + ">" + savedStr + "</" + MyDataDG.columns[k].headerText + ">");
							tempXML.appendChild(should)
						}
					}
				}
				savedXML.appendChild(tempXML)
			}
			WillsavedXML=savedXML.toString();
			doSendToPhp()
		}


		private function doSendToPhp():void
		{
			if (currentIsEdit)
			{
				doDelEditFile()
			}
			else
			{
				doSaveFile();
			}

		}

		private function onFault(re:Object):void
		{
			Alert.show("remoting出错");
		}

		private function getUpFileDate():String
		{
			var mydate:Date=new Date()
			var MyRealMonth:String=checkNumber(Number(mydate.getMonth()) + 1);
			var MyRealDay:String=checkNumber(Number(mydate.getDate()));
			var MyRealMinute:String=String(mydate.getMinutes());
			var MyRealSeconds:String=String(mydate.getSeconds());
			var fileAr:String=mydate.getFullYear() + MyRealMonth + MyRealDay + MyRealMinute + MyRealSeconds;
			//锁定当时执行的时间字符串
			return fileAr
		}

		private function checkNumber(gNum:Number):String
		{
			if (gNum > 10)
			{
				return String(gNum);
			}
			else
			{
				return "0" + gNum
			}
		}
		private var send_type:String;
		private var newName:String

		public function doSaveFile():void
		{
			gatewayUrl="http://192.168.1.102/RichFxTextAreaEditor/amfphp/gateway.php";
			nc.connect(gatewayUrl);
			var sendPath:String="F:/DiDingWebDesign/RichFxTextAreaEditor/upload/codeFile";
			newName=getUpFileDate();
			send_type="xml";
			nc.call("website.TableEditor.saveXML", new Responder(onSaveFileResult, onFault), newName, sendPath, WillsavedXML, send_type);
		}

php脚本代码:


<?php
class TableEditor{
	function saveXML($fileName,$target,$content,$type){
        $target = iconv("utf-8","gbk",$target);
		 $newname = iconv("utf-8","gbk",$fileName);
	     $newfile = $target."/".$newname;
		if($type!="dir"){
			if($type===""){
				$type = $this->FileExt($this->newname);
			}else{
				$newfile .= ".".$type;
			}
			if(file_exists($newfile)){
				return false;
			}else{
				if($fp = @fopen($newfile,"wb")){
			        flock($fp,LOCK_EX);
				    fwrite($fp,$content);
				    flock($fp,LOCK_UN);
				    fclose($fp);
		             }
				return true;
			}

		}
	}
	function FileExt($filename){
		return trim(substr(strrchr($filename, '.'),1));
	}
}
?>
