java Eclipse插件开发：文本编辑器和多语言的文档验证程序

Question

所以今天我有两个问题：

1. 我想为文本编辑器开发一个文档验证器，当我用一个通用编辑器生成Eclipse插件时，它正在为XML创建一个验证器，我想把它改为文本编辑器。有人知道怎么做吗

           DocumentBuilder documentBuilder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
           documentBuilder.parse(new InputSource(reader));
       } catch (Exception ex) {
           try {
               if (this.marker != null)
                   this.marker.delete();
               this.marker = file.createMarker(IMarker.PROBLEM);
               this.marker.setAttribute(IMarker.SEVERITY, IMarker.SEVERITY_WARNING);
               this.marker.setAttribute(IMarker.MESSAGE, "nadav");
               // if (ex instanceof SAXParseException) {
               // SAXParseException saxParseException = (SAXParseException)ex;
               // int lineNumber = saxParseException.getLineNumber();
               // int offset = event.getDocument().getLineInformation(lineNumber -
               // 1).getOffset() + saxParseException.getColumnNumber() - 1;
               // this.marker.setAttribute(IMarker.LINE_NUMBER, lineNumber);
               // this.marker.setAttribute(IMarker.CHAR_START, offset);
               // this.marker.setAttribute(IMarker.CHAR_END, offset + 1);
               // }
           } catch (Exception e) {
               // e.printStackTrace();
           }
       }
   

   这里只是将文档解析为XML，这就是eclipse为我编写的代码

2. 我有行规则作为SingleLineRule和WordRule，但我的问题是多行规则，因为它看起来不像是两行（3行或更多行）后的多行，它不匹配。我能用它做什么？ 这是我的密码：

   RuleBasedScanner scanner = new RuleBasedScanner();
   IRule[] rules = new IRule[5];
   rules[2] = new SingleLineRule("\"", "\"", new Token(stringAttribute));
   rules[3] = new MultiLineRule("/*", "*/", new Token(commentAttribute));
   rules[4] = new SingleLineRule("//", null, new Token(commentAttribute));
   rules[1] = new NumberRule(new Token(number));
   WordRule rule = new WordRule(new IWordDetector() {
   
       @Override
       public boolean isWordStart(char c) {
           // TODO Auto-generated method stub
           return Character.isJavaIdentifierStart(c);
       }
   
       @Override
       public boolean isWordPart(char c) {
           // TODO Auto-generated method stub
           return Character.isLetterOrDigit(c);
       }
   }, new Token(new TextAttribute(new Color(Display.getCurrent(), new RGB(0, 0, 0)))), true);
   for (int i = 0; i < keywords.length; i++) {
       if(keywords[i].equals("#define") || keywords[i].equals("#include"))
           rule.addWord(keywords[i].toLowerCase(), new Token(define));
       else
           rule.addWord(keywords[i].toLowerCase(), new Token(wordAttribute));
   }
   rules[0] = rule;
   scanner.setRules(rules);
   DefaultDamagerRepairer dr = new DefaultDamagerRepairer(scanner);
   this.setDamager(dr, IDocument.DEFAULT_CONTENT_TYPE);
   this.setRepairer(dr, IDocument.DEFAULT_CONTENT_TYPE);
