我在 arrayList 中有一些 xml 文件,例如 A.xml B.xml
我想合并一些节点,而其余节点保持使用 java.我是新手,所以我不知道该怎么做。
一个xml:
<?xml version="1.0" encoding="UTF-8"?>
<nta>
<declaration>
bool A, B;
bool C;
</declaration>
<template>
<location id="1" x="10" y="10"/>
<transition>
<source ref="3"/>
</transition>
</template>
<system> system AND;</system>
</nta>
B.xml:
<?xml version="1.0" encoding="UTF-8"?>
<nta>
<declaration>
int f,k;
bool D;
</declaration>
<template>
<location id="100" x="40" y="89"/>
<transition>
<source col="9"/>
</transition>
</template>
<system> system OR;</system>
</nta>
和输出:
<?xml version="1.0" encoding="UTF-8"?>
<nta>
<declaration>
bool A, B;
bool C;
int f,k;
bool D;
</declaration>
<template>
<location id="1" x="10" y="10"/>
<transition>
<source ref="3"/>
</transition>
</template>
<template>
<location id="100" x="40" y="89"/>
<transition>
<source col="9"/>
</transition>
</template>
<system> system AND, OR;</system>
</nta>
基本上我想合并
declaration
和 system
,其余的在输出 xml 文件中是串行的。如何使用 JAVA 做到这一点?对不起,帖子太长了!!! 最佳答案
与其他可用的 XML 处理 API 相比,对我来说,DOMBuilder
和 SAXBuilder
JDOM 更适合:
这是合并两个 XML 文档的完整工作示例:
SAXBuilder builder = new SAXBuilder();
Document doc1 = builder.build(new File("E:\\XML1.xml"));
Document doc2 = builder.build(new File("E:\\XML2.xml"));
String rootName = doc1.getRootElement().getName();
Element newRoot = new Element(rootName);
Document newDoc = new Document(newRoot);
Element root1 = doc1.getRootElement();
Element root2 = doc2.getRootElement();
// creating declaraion element by merging the declaration content
Element declaration = new Element("declaration");
declaration.addContent(root1.getChildText("declaration"));
declaration.addContent(root2.getChildText("declaration"));
newRoot.addContent(declaration); // add declaration element to new document
newRoot.addContent(root1.getChild("template").clone());
// directly adding template from document XML1,
//after getting template child,
//it needs to be cloned to detached from its parent
newRoot.addContent(root2.getChild("template").clone());
// same for document XML2
/*** now code yourself for system element here ***/
XMLOutputter outputter = new XMLOutputter();
outputter.output(newDoc, System.out);
// output the new doc, pass your OutputStream to this function
关于java - 使用JAVA合并多个XML文件的不同节点,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/19316556/
