java 生成xml并转为字符串的方法

如下所示：

import javax.xml.parsers.documentbuilderfactory;
import javax.xml.parsers.documentbuilder;
import javax.xml.transform.transformerfactory;
import javax.xml.transform.outputkeys;
import javax.xml.transform.transformer;
import javax.xml.transform.dom.domsource;
import javax.xml.transform.stream.streamresult;
 
import org.apache.commons.io.output.bytearrayoutputstream;
 
import org.w3c.dom.document;
import org.w3c.dom.element;
 
public class test {
	
	private string createxml() {
		string xmlstring = "";
 
		documentbuilderfactory factory = documentbuilderfactory.newinstance();
		try {
			documentbuilder builder = factory.newdocumentbuilder();
			document document = builder.newdocument();
			document.setxmlstandalone(true);
 
			element iteminfo = document.createelement("iteminfo");
			document.appendchild(iteminfo);
 
			element itemstatistics = document.createelement("itemstatistics");
			itemstatistics.settextcontent("商品统计");
			iteminfo.appendchild(itemstatistics);
 
			element items = document.createelement("items");
			iteminfo.appendchild(items);
			// 此处可以循环添加
			element item = document.createelement("item");
			items.appendchild(item);
 
			element itemname = document.createelement("itemname");
			itemname.settextcontent("iphone");
			item.appendchild(itemname);
 
			element itemnum = document.createelement("itemnum");
			itemnum.settextcontent("3");
			item.appendchild(itemnum);
 
			element itemvalue = document.createelement("itemvalue");
			itemvalue.settextcontent("1000000");
			item.appendchild(itemvalue);
 
			element remark = document.createelement("remark");
			remark.settextcontent("配送");
			iteminfo.appendchild(remark);
 
			transformerfactory transfactory = transformerfactory.newinstance();
			transformer transformer = transfactory.newtransformer();
			transformer.setoutputproperty(outputkeys.indent, "yes");
			domsource domsource = new domsource(document);
 
			// xml transform string
			bytearrayoutputstream bos = new bytearrayoutputstream();
			transformer.transform(domsource, new streamresult(bos));
			xmlstring = bos.tostring();
			system.out.println(xmlstring);
		} catch (exception e) {
			e.printstacktrace();
		}
 
		return xmlstring;
	}
}

结果：

<?xml version="1.0" encoding="utf-8"?>
<iteminfo>
<itemstatistics>商品统计</itemstatistics>
<items>
<item>
<itemname>iphone</itemname>
<itemnum>3</itemnum>
<itemvalue>1000000</itemvalue>
</item>
</items>
<remark>配送</remark>
</iteminfo>

去掉头文件

<?xml version="1.0" encoding="utf-8"?>

的办法暂时只能想到：

xmlstring.substring(38)
