主要用于Android的values资源文件下的资源整合
一，代码
public class DuplicateFileContentDelete {
public static void main(String[] args) throws DocumentException, IOException {
String secretResPath = "/Users/jiajia/Downloads/app/res";//这个是保持不变，用来比较的文件夹
String testResPath = "/Users/jiajia/Downloads/res";//这个是我最后的标准，这个里面如果有跟secretResPath重复的资源可以删除，复写
File filesCompare = new File(secretResPath);
//删除的资源输出
String deleteTxt = "/Users/jiajia/Downloads/detele.txt";
File files = new File(testResPath);
File[] listFiles = files.listFiles();
for (File listFile : listFiles) {//res文件下的所有文件
if (listFile.isDirectory() && listFile.getName().contains("values")) {//找到所有的value文件夹
File[] childListFiles = listFile.listFiles();
for (File childListFile : childListFiles) {//找到values文件夹下的所有文件
//System.out.println(childListFile.getAbsolutePath());
//读取XML文件,获得document对象.
SAXReader reader = new SAXReader();
Document document = reader.read(childListFile.getAbsolutePath());
Element rootElement = document.getRootElement();//获取文件的根结点
//System.out.println(rootElement.getName());
//对某节点下的所有子节点进行遍历.
for (Iterator it = rootElement.elementIterator(); it.hasNext(); ) {
Element element = (Element) it.next();
//System.out.println(element.getName());//子节点的节点名
// Iterator<Attribute> iterator = element.attributeIterator();
// for(Iterator itt = iterator;itt.hasNext();){
// //获取子节点的属性
// Attribute next = (Attribute) itt.next();
// System.out.println(next.getName() + "==" + next.getValue());
// }
Attribute attribute = element.attribute("name");//获取子节点属性"name"
// attribute.getValue();//节点属性"name"对应的值
// System.out.println(attribute.getName() + "==" + attribute.getValue());
for (File listFileCompare : filesCompare.listFiles()) {//res文件下的所有文件
if (listFileCompare.isDirectory() && listFileCompare.getName().contains("values")) {//找到所有的value文件夹
File[] childListFilesCompares = listFileCompare.listFiles();
for (File childListFileCompare : childListFilesCompares) {//找到values文件夹下的所有文件
//读取XML文件,获得document对象.
SAXReader readerCompare = new SAXReader();
Document documentCompare = readerCompare.read(childListFileCompare.getAbsolutePath());
Element rootElementCompare = documentCompare.getRootElement();//获取文件的根结点
//对某节点下的所有子节点进行遍历.
for (Iterator itCompare = rootElementCompare.elementIterator(); itCompare.hasNext(); ) {
Element elementCompare = (Element) itCompare.next();
Attribute attributeCompare = elementCompare.attribute("name");//获取子节点属性"name"
if (element.getName().equals(elementCompare.getName()) && attribute.getValue().equals(attributeCompare.getValue())) {
// System.out.println("DELTE_ELEMENT" + childListFile.getAbsolutePath());
// System.out.println("DELTE_ELEMENT" + element.getName());
// System.out.println("DELTE_ELEMENT" + attribute.getName() + "==" + attribute.getValue());
FileOutputStream delete = new FileOutputStream(deleteTxt, true);
delete.write((childListFile.getAbsolutePath() + "==" + childListFileCompare.getAbsolutePath()).getBytes());
delete.write("\r\n".getBytes());
delete.write(attribute.getValue().getBytes());
delete.write("\r\n".getBytes());
delete.write("\r\n".getBytes());
delete.close();
rootElement.remove(element);//移除test里面的元素
//将修改后的document写出覆盖原本的
//指定文件输出的位置
FileOutputStream out = new FileOutputStream(childListFile.getAbsolutePath());
// 指定文本的写出的格式：
OutputFormat format = OutputFormat.createPrettyPrint(); //漂亮格式：有空格换行
format.setEncoding("UTF-8");
//1.创建写出对象
XMLWriter writer = new XMLWriter(out, format);
//2.写出Document对象
writer.write(document);
//3.关闭流
writer.close();
}
}
}
}
}
}
}
}
}
}
}
二，Android studio下的依赖添加
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation files('/Users/jiajia/Downloads/dom4j-2.1.1.jar')
}
三，jar文件
自己可以去网上下载对应dom4j-2.1.1.jar
