如何将节点从xml文档附加到现有的xml文档 [英] how to append node from xml document to existing xml document
本文介绍了如何将节点从xml文档附加到现有的xml文档的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
< tournaments>
< tournament>
< name> a< / name>
< / tournament>
< tournament>
< name> b< / name>
< / tournament>
< tournament>
< name> c< / name>
< / tournament>
< / tournaments>
广告然后我在b.xml中有一个比赛
< tournament>
< name> d< / name>
< / tournament>
如何将文件b.xml加载到a.xml作为另一场比赛?
所以这就是我想要的:
< tournaments>
< tournament>
< name> a< / name>
< / tournament>
< tournament>
< name> b< / name>
< / tournament>
< tournament>
< name> c< / name>
< / tournament>
< tournament>
< name> d< / name>
< / tournament>
< / tournaments>
解决方案
- 获取节点从第一个添加文档;
- 采用节点(参见文档.adopt(Node))从第一个文档到第二个文档;
- Appent采用 Node 作为一个小孩第二文档结构(请参阅节点。 appendChild(Node)。
更新。
代码:
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = documentBuilderFactory.newDocumentBuilder();
文件比赛= builder.parse(new File(b.xml));
文件比赛= builder.parse(new File(a.xml));
节点tournamentElement = tournament.getFirstChild();
Node ndetournament = tournaments.getDocumentElement();
Node firstDocImportedNode = tournaments.adoptNode(tournamentElement);
ndetournament.appendChild(firstDocImportedNode);
TransformerFactory transformerFactory = TransformerFactory.newInstance();
变压器变压器= transformerFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT,yes);
transformer.transform(new DOMSource(tournaments)),新的StreamResult(System.out));
结果:
code><?xml version =1.0encoding =UTF-8standalone =否?>
<锦标赛>
< tournament>
< name> a< / name>
< / tournament>
< tournament>
< name> b< / name>
< / tournament>
< tournament>
< name> c< / name>
< / tournament>
< tournament>
< name> d< / name>
< / tournament>
< / tournaments>
I have list of tournaments in my a.xml:
<tournaments>
<tournament>
<name>a</name>
</tournament>
<tournament>
<name>b</name>
</tournament>
<tournament>
<name>c</name>
</tournament>
</tournaments>
ad then I have one tournament in b.xml
<tournament>
<name>d</name>
</tournament>
How I can apend document b.xml to a.xml into as another tournament ?
so this is what I want:
<tournaments>
<tournament>
<name>a</name>
</tournament>
<tournament>
<name>b</name>
</tournament>
<tournament>
<name>c</name>
</tournament>
<tournament>
<name>d</name>
</tournament>
</tournaments>
解决方案
- Get Node to add from first Document;
- Adopt Node (see Document.adopt(Node)) from first Document to the second Document;
- Appent adopted Node as a child to second Document structure (see Node.appendChild(Node).
Update. Code:
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = documentBuilderFactory.newDocumentBuilder();
Document tournament = builder.parse(new File("b.xml"));
Document tournaments = builder.parse(new File("a.xml"));
Node tournamentElement = tournament.getFirstChild();
Node ndetournament = tournaments.getDocumentElement();
Node firstDocImportedNode = tournaments.adoptNode(tournamentElement);
ndetournament.appendChild(firstDocImportedNode);
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.transform(new DOMSource(tournaments), new StreamResult(System.out));
Result:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<tournaments>
<tournament>
<name>a</name>
</tournament>
<tournament>
<name>b</name>
</tournament>
<tournament>
<name>c</name>
</tournament>
<tournament>
<name>d</name>
</tournament>
</tournaments>
