拆分xml而不在Java中创建新元素到另一个文件 [英] Splitting an xml without creating new element in java to another file
问题描述
下面是我的XML，我想将其拆分为另一个文件，而无需 创建一个新元素. 有没有一种方法可以将基于子节点的XML拆分为另一个XML 没有创建新标签?
Below is my XML and I want to split that into another file without creating a new element. Is there a way to split that XML based on the child node to another XML without creating new tag?
File 1.xml
<Envelope>
<Data>
<SomeData>SampleData</SomeData>
<NextData>NextData</NextData>
</Data>
<Body>
<Name>ABC</Name>
<Age>12</Age>
<Country>India</Country>
</Body>
</Envelope>
文件1是现有文件，我希望文件2仅包含正文内容 如下图所示
File1 is an existing one and I want file2 to have only contents of body as shown below
File2.xml
<Body>
<Name>ABC</Name>
<Age>12</Age>
<Country>India</Country>
</Body>
我也希望file2是一个新文件，但我不想 创建任何新元素. 我在这里引用的示例只能做到这一点 通过创建一个新元素 下面的链接使用创建新元素
Also I want the file2 to be a new file but I don't want to have any new elements created. The examples i referred here had a way to do this only by creating a new element Below link uses creating new element

我提到的代码:
public class XmlSplit {
public static void main(String [] args) throws Exception {
File input = new File("input.xml");
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
Document doc = dbf.newDocumentBuilder().parse(input);
XPath xpath = XPathFactory.newInstance().newXPath();
NodeList nodes = (NodeList) xpath.evaluate("//T0020/IRP_ACCOUNT", doc, XPathConstants.NODESET);
int itemsPerFile = 5;
int fileNumber = 0;
Document currentDoc = dbf.newDocumentBuilder().newDocument();
Node rootNode = currentDoc.createElement("T0020");
File currentFile = new File(fileNumber+".xml");
for (int i=1; i <= nodes.getLength(); i++) {
Node imported = currentDoc.importNode(nodes.item(i-1), true);
rootNode.appendChild(imported);
if (i % itemsPerFile == 0) {
writeToFile(rootNode, currentFile);
rootNode = currentDoc.createElement("T0020");
currentFile = new File((++fileNumber)+".xml");
}
}
writeToFile(rootNode, currentFile);
}
private static void writeToFile(Node node, File file) throws Exception {
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.transform(new DOMSource(node), new StreamResult(new FileWriter(file)));
}
}
推荐答案
我将使用XSLT转换并将其转换.
Java代码:
I would use the XSLT transformation and transform it.
Java Codes:
TransformerFactory factory = TransformerFactory.newInstance();
Source xslt = new StreamSource(new File("Split.xslt"));
Transformer transformer = factory.newTransformer(xslt);
Source text = new StreamSource(new File("File1.xml"));
transformer.transform(text, new StreamResult(new File("File2.xml")));
文件:Split.xslt
File: Split.xslt
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output indent="yes" />
<xsl:template match="/">
<xsl:copy-of select="/Envelope/Body"/>
</xsl:template>
</xsl:stylesheet>
输出文件:
<?xml version="1.0" encoding="UTF-8"?>
<Body>
<Name>ABC</Name>
<Age>12</Age>
<Country>India</Country>
</Body>
