我的要求是，如果其子元素PARVW"的值是SS"，我想从文件中删除整个段E1EDKA1".在我的情况下，我想删除 PARVW 为 SS 的E1EDKA1"的 3 个片段
My requirment is that I want to remove the entire segment "E1EDKA1" from the file if its child element "PARVW" is coming with value "SS". In my case I want to remove the 3 segments of "E1EDKA1" whose PARVW is coming as SS
我从我这边尝试:我的代码如下:
I tried from my side: My code is below:
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(fis);
NodeList nList = doc.getElementsByTagName("E1EDKA1");
System.out.println(nList.getLength());
if (nList != null && nList.getLength() > 0) {
for (int i = 0; i < nList.getLength();i++) {
Node node = nList.item(i);
// System.out.println(node);
Element e = (Element) node;
NodeList nodeList = e.getElementsByTagName("PARVW");
String title = nodeList.item(0).getChildNodes().item(0).getNodeValue();
System.out.println(title);
if (title.equals("SS")) {
System.out.println("Test");
doc.getFirstChild().removeChild(node);
}
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(new File("C:/Users/ssourav/Desktop/Idoc12_out123.xml"));
transformer.transform(source, result);
请帮助我获得此输出并建议我代码中的问题在哪里.实际上，程序在遇到第一个SS"值时退出，并且没有任何内容写入输出文件.
Please help me to get this output and suggest me where is the problem in the code. actually the program gets out as it encounters the first "SS" value and nothing has been written to the output file.
推荐答案
如果什么都没写，我想你会得到一个例外.你抓到了没有踪迹吗?
If nothing is written I think you get an exception. Are you catching it with no trace?
尝试以这种方式移除节点:e.getParentNode().removeChild(e);
Try removing the node this way: e.getParentNode().removeChild(e);
这篇关于从 Java 中的 XML 文件中删除节点的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
