小编Mar*_*ouh的帖子

我有以下xml:

<table1>
    <row0>
        <column1>String</column1>
        <column2>int</column2>
    </row0>

    <row1>
        <column1>aa</column1>
        <column2>65432</column2>
    </row1>

    <row2>
        <column1>ww</column1>
        <column2>1111</column2>
    </row2>

    <row3>
        <column1>fff</column1>
        <column2>333</column2>
    </row3>

    <row4>
        <column1>jj</column1>
        <column2>2</column2>
    </row4>
</table1>

我想删除节点row3及其元素.我在java.how中写这个XML文件来做那个？我在另一篇文章中看到了这段代码但却无法理解

public static void main(String[] args) throws Exception {
    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
    Document document = dbf.newDocumentBuilder().parse(new File("input.xml"));

    XPathFactory xpf = XPathFactory.newInstance();
    XPath xpath = xpf.newXPath();
    XPathExpression expression = xpath.compile("//A/B[C/E/text()=13]");

    Node b13Node = (Node) expression.evaluate(document, XPathConstants.NODE);
    b13Node.getParentNode().removeChild(b13Node);

    TransformerFactory tf = TransformerFactory.newInstance();
    Transformer t = tf.newTransformer();
    t.transform(new DOMSource(document), new StreamResult(System.out));
}

我有以下XML文件：

<Tables>
    <table>
        <row></row>
    </table>
<Tables>

我想将其编辑为：

<Tables>
    <table>
        <row>some value</row>
    </table>
<Tables>

我使用文件编写器编写XML文件。我该如何编辑？

发现我创建的临时文件包含编辑内容，然后删除原始文件并重命名该临时文件。还有其他办法吗？

那是我编写文件的代码：

public boolean createTable(String path, String name, String[] properties) throws IOException {
    FileWriter writer = new FileWriter(path);
    writer.write("<Tables>");
    writer.write("\t<" + name + ">");
    for(int i=0; i<properties.length; i++){
        writer.write("\t\t<" + properties[0] + "></" + properties[0] + ">");
    }
    writer.write("\t</" + name + ">");
    writer.write("</Tables>");
    writer.close();
    return false;
}
