java如何将Document转换为String。但是空标签是&lt;&gt;</> ，不是</>

Question

In my project ,my company requires empty tag use <a></a> form ,rather than <a/> form. And Haven't redundant enters and spaces. But I don't know how to do it. You can use any way to do it.

Here is I generate xml(String) from Document:

< Header>< Fund_Id>1< /Fund_Id>< Trade_Code/>< Error_Code/>< Error_Message/>< /Header>

To the empty tags, I want it is form. example:

< Header>< Fund_Id>1< /Fund_Id>< Trade_Code>< /Trade_Code>< Error_Code>< /Error_Code>< Error_Message>< /Error_Message>< /Header>

Thank you very much.

I have resolved my question by this methods. Convert the String after converting Document to String.

public static String xmlChange(String xmlStr)
{
    if(xmlStr!=null)
    {
        for (int i = 0; i < xmlStr.length();)
        {
            int index=xmlStr.indexOf("/>",i);
            if(index>0)
            {
                String tempStr = xmlStr.substring(i, index + 2);
                int leftIndex=tempStr.lastIndexOf("<");
                String old= tempStr.substring(leftIndex);
                String _new=old.replace("/","")+old.replace("/","").replace("<","</");
                i=index+2;
                xmlStr=xmlStr.replace(old,_new);
            }
            else
            {
                break;
            }
        }
        xmlStr=xmlStr.replaceAll("\r|\n", "");
    }
    return xmlStr;
}
