最近公司要做应用集成，涉及到很多的接口集成，而传入过来的XML并不是标准的XML所以我想把非标准的XML转成标准的，以便于用标准的XML可以直接当做表插入数据库。
这是我所写的一个测试类：
package com.dcms.util.webServices;
public class ECToXML {
public static String[] split(String str , char ch){
if(str==null){
return null;
}
if(str.charAt(0)==ch){
str = str.substring(1);
}
if(str.charAt(str.length()-1)==ch){
str = str.substring(0,str.length()-1);
}
return str.split(ch+"");
}
/**
* @param args
*/
public static void main(String[] args) {
String xml = "<STD_IN Origin=\"TIPTOP\"><Service Name=\"SetData\"><ObjectID>Item</ObjectID><ServiceId>TIPTOP</ServiceId><Operate>ADJUST</Operate><Seperator>^*^</Seperator><User>cdlc</User><Factory>Unknown</Factory><IgnoreError>N</IgnoreError><Data Format=\"Join\"><DataSet Field=\"productId^*^productName^*^scale^*^assort2^*^type1^*^packageSize^*^resellPrice^*^assortment^*^barcode^*^invCount^*^invUnit^*^mInvClass^*^preDays^*^status^*^updateDate^*^type^*^stInPrice^*^itemSeq^*^packageNo^*^quotiety^*^length^*^width^*^height^*^volume^*^netWeight^*^grossWeight^*^sceneId^*^sceneName^*^brandId^*^brandName^*^invUnitName^*^itemSeqName^*^unit^*^unitName^*^poUnit^*^poUnitName\"><Row Data=\"902000001^*^J2551JA长几^*^1418*875*380^*^001^*^B^*^^*^222^*^333^*^^*^53^*^PCS^*^S091^*^0^*^Y^*^2010-05-04 00:00:00^*^0^*^1961^*^L02^*^1^*^1^*^1490^*^940^*^60^*^.084^*^46^*^48^*^101^*^客厅^*^L02^*^依洛歌^*^PCS^*^依洛歌^*^PCS^*^PCS^*^PCS^*^PCS\"/><Row Data=\"902000001^*^J2551JA长几^*^1418*875*380^*^001^*^B^*^^*^0^*^001^*^^*^53^*^PCS^*^S091^*^0^*^Y^*^2010-05-04 00:00:00^*^0^*^1961^*^L02^*^2^*^1^*^1360^*^960^*^130^*^.17^*^44^*^46^*^101^*^客厅^*^L02^*^依洛歌^*^PCS^*^依洛歌^*^PCS^*^PCS^*^PCS^*^PCS\"/></DataSet></Data></Service></STD_IN>";
LBToECXML ec = new LBToECXML();
String tt = ec.toXML(xml);
// String temp = "abbcbbdbbebb";
// int a = temp.indexOf("bb");
// String temp1 = temp.substring(0, temp.indexOf("bb"));
// System.out.println(temp1);
// System.out.println(a);
}
}
