How to insert/replace XML tag in XmlDocument? | I have a `XmlDocument` in java, created with the `Weblogic XmlDocument` parser.


I want to replace the content of a tag in this `XMLDocument` with my own data, or insert the tag if it isn't there.



```
<customdata>
   <tag1 />
   <tag2>mfkdslmlfkm</tag2>
   <location />
   <tag3 />
</customdata>

```

For example I want to insert a URL in the location tag:



```
<location>http://something</location>

```

but otherwise leave the XML as is.


Currently I use a `XMLCursor`:



```
    XmlObject xmlobj = XmlObject.Factory.parse(a.getCustomData(), options);
    XmlCursor xmlcur = xmlobj.newCursor();

    while (xmlcur.hasNextToken()) {
      boolean found = false;
      if (xmlcur.isStart() && "schema-location".equals(xmlcur.getName().toString())) {
        xmlcur.setTextValue("http://replaced");
        System.out.println("replaced");
        found = true;
      } else if (xmlcur.isStart() && "customdata".equals(xmlcur.getName().toString())) {
        xmlcur.push();
      } else if (xmlcur.isEnddoc()) {
        if (!found) {
          xmlcur.pop();
          xmlcur.toEndToken();
          xmlcur.insertElementWithText("schema-location", "http://inserted");
          System.out.println("inserted");
        }

      }
      xmlcur.toNextToken();
    }

```

I tried to find a "quick" `xquery` way to do this since the `XmlDocument` has an `execQuery` method, but didn't find it very easy. 


Do anyone have a better way than this? It seems a bit elaborate.
