xmlHttp.responseXML.getElementsByTagName cannot get the value, urgent

皮貂皮的羊

If the requested address is a static XML file, it can be parsed normally, but when the request address is replaced with JSP, the XML content is written out in response.getWriter (). Write in the JSP, it cannot be received by the client. why? The XML content has been printed on the server:
<? xml version = "1.0" encoding = "UTF-8"?> <root> <ShopMember name = "zyaa"> <value> afaf </ value> </ ShopMember> <ShopMember name = "zyaaa"> <value > zyaa_a </ value> </ ShopMember> </ root>

Checked, it is said that you have to use Servlet, JSP seems not to work, I try it out, depressed.

Set the contenttype in response, set to application/xml should be no problem

Your jsp
response.setContentType("text/xml;charset=GBK");
StringBuffer buf = new StringBuffer();
buf.append("<?xml version=\"1.0\" encoding=\"GBK\"?>");
buf.append("<root> ");
while(rs.next())
{
buf.append("<node id='"+rs.getString(1)+"' hasChildren='"+rs.getString(4)+"' pro='"+rs.getString(5)+"'> "+ rs.getString(3)+ "</node>");
}
buf.append(" </root>");
out.print(buf);

This is the main problem. Although you see the print, it may be in html format instead of xml format. Alert ajax.responseXML and ajax.responseText to know what's going on.

I have also encountered what I said. Cannot get xml when calling jsp page. So consider directly using the class to output xml. You can use ajax to directly access the servlet. If you have used the struts framework, you can directly access the action. Use out.print to output an xml file to memory. This kind of code is available online.

It should be responseXML, you will know it by checking it, it was useless for a while, don't remember.
This has nothing to do with using jsp or servlet.

In fact, there is a very simple test method, just use IE to directly access your jsp page, and see if IE is displayed in the xml document format (in this case, the xml document can be contracted) or the normal string displays the jsp page.
If it is displayed in xml document format, then your jsp will be no problem. I think yours is definitely not displayed in xml document format.

You can only use Servlet, not jsp, I don't know why.
