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)
