我的a.xml中有锦标赛列表:
<tournaments>
<tournament>
<name>a</name>
</tournament>
<tournament>
<name>b</name>
</tournament>
<tournament>
<name>c</name>
</tournament>
</tournaments>
ad然后我在b.xml中有一个锦标赛
<tournament>
<name>d</name>
</tournament>
如何将b.xml文档作为另一个锦标赛添加到a.xml中?
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>

更新。 代码:
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));
结果:
<?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>

这对你有用吗?

ndetournament.appendChild(firstDocImportedNode);
} catch (Exception e) {
e.printStackTrace();
}
}
private static Document getCurrentTournaments() throws Exception{
DocumentBuilder builder = dbFactory.newDocumentBuilder();
Document docTournament = builder.parse(new StringBufferInputStream(tournamentData));
return docTournament;
}
private static Element getNewTournament() throws Exception{
DocumentBuilder builder = dbFactory.newDocumentBuilder();
Document newTournament = builder.parse(new StringBufferInputStream(tournamentData));
Element tournament = newTournament.getDocumentElement();
return tournament;
}
}
您可以修改getXXXX()函数套件自己的代码
