Remove XML attribute using JDOM API?

问题

I have a JDOM element like the following

Example:XML(JDOM Element)

<Details>
<Uniqueno>11111</Uniqueno>
<ROWSET name="Persons">
<ROW num="1">
<Name>60821894</Name>
<Age>938338789</Age>
</ROW>
<ROW num="2">
<Name>60821894</Name>
<Age>938338789</Age>
</ROW>
</ROWSET>
</Details>

I want to convert like:

<Details>
<Uniqueno>11111</Uniqueno>

<ROW num="1">
<Name>60821894</Name>
<Age>938338789</Age>
</ROW>
<ROW num="2">
<Name>60821894</Name>
<Age>938338789</Age>
</ROW>

</Details>

note:ROWSET element is removed

I want to remove the element using JDOM API?

回答1:

What have you already tried ?

Find the Details tag (which is the document root)
Find the ROWSET tag
for each ROW tag in ROWSET call the detach() method on the node and append() this detached node to the Details tag.
Delete the ROWSET tag.

With some sample code:

// 1
Element details = doc.getRootElement();
// 2
Element rowset = details.getChild("ROWSET");
// 3
for (Element row: rowset.getChildren()) {
    Element r = row.detach();
    details.appendChild(r);
}
// 4
details.removeChild(rowset);

Not tested, for more info check the JDOM API.

If you are using JDOM 2.0.x you can do something like:

for (Element rowset : details.getChildren("ROWSET")) {
    rowset.detach();
    for (Content c : rowset.getContent()) {
         details.addContent(c.detach());
    }
}

If you are using JDOM 1.x you can do something similar, but with more casts....
