如何使用SAX在1类中一次解析2个xml文件

Question

我如何“强制”解析器方法使用第二个文件并制作第二张地图？
我为1个文件进行了xml解析和映射（LinkedHashMap）。
如何处理其他文件？

在我的代码中，您可以找到2个parser实例，2个linkedHashMap。
但是方法仅适用于1个文件，因为我不知道如何指向将其他文件用于方法。

到目前为止，我的代码是：

 package xml_strings; import java.util.LinkedHashMap; import javax.xml.parsers.SAXParser; import javax.xml.parsers.SAXParserFactory; import org.xml.sax.Attributes; import org.xml.sax.SAXException; import org.xml.sax.helpers.DefaultHandler; public class ReadingResourcesWithSax { static LinkedHashMap<String, String> mapaEn = new LinkedHashMap<String, String>(); static LinkedHashMap<String, String> mapaPl = new LinkedHashMap<String, String>(); public static void main(String[] args) throws Exception { XmlHandler xmlHandler = new XmlHandler(); SAXParserFactory factory = SAXParserFactory.newInstance(); SAXParser saxParser = factory.newSAXParser(); saxParser.parse("strings1.xml", xmlHandler); SAXParser saxParser1 = factory.newSAXParser(); saxParser1.parse("strings2.xml", xmlHandler); for (String key : mapaEn.keySet()) { System.out.print(key + "\\n"); System.out.println("<" + mapaEn.get(key) + ">\\n"); } } private static class XmlHandler extends DefaultHandler { private boolean insideStringItem; private String a, b, c; private int i = 0; @Override public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException { if (qName.equals("string")) { insideStringItem = true; a = attributes.getValue("name"); } else if (qName.equals("string-array")) { insideStringItem = true; a = attributes.getValue("name"); c = a; } else if (qName.equals("item")) { insideStringItem = true; a = c + "###" + i; i++; } } @Override public void characters(char[] ch, int start, int length) throws SAXException { if (insideStringItem) { insideStringItem = false; b = new String(ch, start, length); mapaEn.put(a, b); } } @Override public void endElement(String uri, String localName, String qName) throws SAXException { if (qName.equals("string-array")) { i = 0; } } } }

好的，我知道了，也许其他人会在寻找那个解决方案
使用相同的处理程序和相同的方法一次解析多个文件:)

 package xml_strings; import java.util.ArrayList; import java.util.LinkedHashMap; import java.util.List; import java.util.Map; import java.util.Set; import javax.xml.parsers.SAXParser; import javax.xml.parsers.SAXParserFactory; import org.xml.sax.Attributes; import org.xml.sax.SAXException; import org.xml.sax.helpers.DefaultHandler; public class ReadingResourcesWithSax { static Map<String, String> mapaEn = new LinkedHashMap<String, String>(); static Map<String, String> mapaPl = new LinkedHashMap<String, String>(); public static void main(String[] args) throws Exception { XmlHandler xmlHandler = new XmlHandler(); xmlHandler.setMap(mapaEn); SAXParserFactory factory = SAXParserFactory.newInstance(); SAXParser saxParser = factory.newSAXParser(); saxParser.parse("stringsEn.xml", xmlHandler); XmlHandler xmlHandler1 = new XmlHandler(); xmlHandler1.setMap(mapaPl); SAXParserFactory factory1 = SAXParserFactory.newInstance(); SAXParser saxParser1 = factory1.newSAXParser(); saxParser1.parse("stringsPl.xml", xmlHandler1); for (String key : mapaEn.keySet()) { System.out.print(key + "\\n"); System.out.println("<" + mapaEn.get(key) + ">\\n"); } for (String key : mapaPl.keySet()) { System.out.print(key + "\\n"); System.out.println("<" + mapaPl.get(key) + ">\\n"); } List<Map<String, String>> listaMap = new ArrayList<Map<String, String>>(); listaMap.add(mapaEn); listaMap.add(mapaPl); Set<String> keySet = listaMap.get(0).keySet(); for(String key: keySet) { System.out.println(key); for(Map<String, String> map: listaMap) { System.out.println("\\t"+map.get(key)); } } for(Map<String, String> lista : listaMap) { System.out.println("Wartosci dla tego samego klucza : " + lista.get("type_not_saved")); } } private static class XmlHandler extends DefaultHandler { private Map<String, String> map; private boolean insideStringItem; private String a, b, c; private int i = 0; public void setMap(Map<String, String> map) { this.map = map; } public Map<String, String> getMap() { return map; } @Override public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException { if (qName.equals("string")) { insideStringItem = true; a = attributes.getValue("name"); } else if (qName.equals("string-array")) { insideStringItem = true; a = attributes.getValue("name"); map.put(a,"string-array"); c = a; } else if (qName.equals("item")) { insideStringItem = true; a = c + "###" + i; i++; } } @Override public void characters(char[] ch, int start, int length) throws SAXException { if (insideStringItem) { insideStringItem = false; b = new String(ch, start, length); map.put(a, b); } } @Override public void endElement(String uri, String localName, String qName) throws SAXException { if (qName.equals("string-array")) { i = 0; } } } }
