使用removeContent（）从JDOM文档中删除Element

<Geography xmlns:ns=\"some valid namespace\">
    <Country>
        <Region>
            <State>
                <City>
                    <Name></Name>
                    <Population></Population>
                </City>
            </State>
            </Region>
        </Country>
    </Geography>

InputStream is = new FileInputStream(\"C:\\\\Geography.xml\");
SAXBuilder saxBuilder = new SAXBuilder();
Document doc = saxBuilder.build(is);

XPath xpath = XPath.newInstance(\"/*/Country/Region/State/City\");
Element el = (Element) xpath.selectSingleNode(doc);
boolean b = doc.removeContent(el);

removeContent()

City

doc

false

Name

Population

Parent

Parent p = el.getParent();
boolean s = p.removeContent(new Element(\"City\"));
