我有一个奇怪的问题（至少它看起来这样），当在textPane中搜索一个字符串，我得到一个额外的索引每个行号搜索和当使用StyledDoc经文只是从textPane获取文本时返回。我从同一个窗格中获取相同的文本，只是一个来自纯文本，另一个来自样式文档。我在这里错过了什么。我将尽力列出我正在使用的两个版本之间的许多变化。StyledDocument增加额外的计数indexof文件的每一行
的纯文本版本：
public int displayXMLFile(String path, int target){
InputStreamReader inputStream;
FileInputStream fileStream;
BufferedReader buffReader;
if(target == 1){
try{
File file = new File(path);
fileStream = new FileInputStream(file);
inputStream = new InputStreamReader(fileStream,"UTF-8");
buffReader = new BufferedReader(inputStream);
StringBuffer content = new StringBuffer("");
String line = "";
while((line = buffReader.readLine())!=null){
content.append(line+"\n");
}
buffReader.close();
xhw.txtDisplay_1.setText(content.toString());
}
catch(Exception e){
e.printStackTrace();
return -1;
}
}
}
诗句风格化文件（没有应用的样式）
protected void openFile(String path, StyledDocument sDoc, int target)
throws BadLocationException {
FileInputStream fileStream;
String file;
if(target == 1){
file = "Openning First File";
} else {
file = "Openning Second File";
}
try {
fileStream = new FileInputStream(path);
// Get the object of DataInputStream
//DataInputStream in = new DataInputStream(fileStream);
ProgressMonitorInputStream in = new ProgressMonitorInputStream(
xw.getContentPane(), file, fileStream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String strLine;
//Read File Line By Line
while ((strLine = br.readLine()) != null) {
sDoc.insertString(sDoc.getLength(), strLine + "\n", sDoc.getStyle("regular"));
xw.updateProgress(target);
}
//Close the input stream
in.close();
} catch (Exception e){//Catch exception if any
System.err.println("Error: " + e.getMessage());
}
这是我如何搜索：
public int searchText(int sPos, int target) throws BadLocationException{
String search = xhw.textSearch.getText();
String contents;
JTextPane searchPane;
if(target == 1){
searchPane = xhw.txtDisplay_1;
} else {
searchPane = xhw.txtDisplay_2;
}
if(xhw.textSearch.getText().isEmpty()){
xhw.displayDialog("Nothing to search for");
highlight(searchPane, null, 0,0);
} else {
contents = searchPane.getText();
// Search for the desired string starting at cursor position
int newPos = contents.indexOf(search, sPos);
// cycle cursor to beginning of doc window
if (newPos == -1 && sPos > 0){
sPos = 0;
newPos = contents.indexOf(search, sPos);
}
if (newPos >= 0) {
// Select occurrence if found
highlight(searchPane, contents, newPos, target);
sPos = newPos + search.length()+1;
} else {
xhw.displayDialog("\"" + search + "\"" + " was not found in File " + target);
}
}
return sPos;
}
示例文件：
<?xml version="1.0" encoding="UTF-8"?>
<AlternateDepartureRoutes>
<AlternateDepartureRoute>
<AdrName>BOIRR</AdrName>
<AdrRouteAlpha>..BROPH..</AdrRouteAlpha>
<TransitionFix>
<FixName>BROPH</FixName>
</TransitionFix>
</AlternateDepartureRoute>
<AlternateDepartureRoute>
</AlternateDepartureRoutes>
我的荧光笔：
public void highlight(JTextPane tPane, String text, int position, int target) throws BadLocationException {
Highlighter highlighter = new DefaultHighlighter();
Highlighter.HighlightPainter painter = new DefaultHighlighter.DefaultHighlightPainter(Color.LIGHT_GRAY);
tPane.setHighlighter(highlighter);
String searchText = xhw.textSearch.getText();
String document = tPane.getText();
int startOfSString = document.indexOf(searchText,position);
if(startOfSString >= 0){
int endOfSString = startOfSString + searchText.length();
highlighter.addHighlight(startOfSString, endOfSString, painter);
tPane.setCaretPosition(endOfSString);
int caretPos = tPane.getCaretPosition();
javax.swing.text.Element root = tPane.getDocument().getDefaultRootElement();
int lineNum = root.getElementIndex(caretPos) +1;
if (target == 1){
xhw.txtLineNum1.setText(Integer.toString(lineNum));
} else if (target == 2){
xhw.txtLineNum2.setText(Integer.toString(lineNum));
} else {
xhw.txtLineNum1.setText(null);
xhw.txtLineNum2.setText(null);
}
} else {
highlighter.removeAllHighlights();
}
}
当我做Alt键搜索用的indexOf（）我得到40的纯文本（这是它应该返回什么）和41与风格的文档搜索时。对于Alt出现在我得到的每一个额外的行以及额外的索引（以便indexof（）调用在第3行中返回2以上）。这发生在找到的每一条附加线上。我错过了明显的东西吗？ （如果我需要将它推送到一个较小的单个类，以便于检查，那么稍后我可以做更多的时间）。
在此先感谢...
