Java双引号

Question

I need to find a way to check for double quotes in a string to I can write the output to an XML document and then open in word. I figured out how to look for a single quote like (') but the double quote is throwing a error in my XML document.

     private String checkForDoubleQuote(String l) {
    String newLine = new String();
    char d = '\"';


    for (int index=0;index < l.length();index++) {
        if(l.indexOf(8220)>-1 || l.indexOf(8221)>-1 ||
                 l.indexOf(34)>-1) {
            char c = l.charAt(index);     
             newLine += c;
        } else {
            char c = l.charAt(index);     
            newLine += c;
        }

    }
    System.out.println("new Line --> " + newLine);
    return newLine;
}

Here is the XML word output that is causing be trouble: (the two square boxes are x93 and x94 in the XML code.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<?mso-application progid="Word.Document"?>
<w:wordDocument xmlns:w="http://schemas.microsoft.com/office/word/2003/wordml">

If you want to strip all the singlequote and doublequote characters out of a string, as well as those silly special quotes that MS Office throws in, here is a method to do it:

public static String stripQuote(String l) {
    StringBuffer newLine = new StringBuffer();

    for (int i=0; i<l.length(); i++) {
        char ch = l.charAt(i);
        if (ch==8220 || ch==8221 || ch=='\"' || ch=='\'') {
            //do nothing
        }
        else {
            newLine.append(ch);
        }
    }
    return newLine.toString();
}

The code you used in the example constructs many strings over the processing of the line. This constructs only one.

You also need to worry about anglebracket characters ("<") as well.

However, if instead of stripping them out, you want to encode them properly in XML, you might do this:

public static String encodeQuote(String l) {
    StringBuffer newLine = new StringBuffer();

    for (int i=0; i<l.length(); i++) {
        char ch = l.charAt(i);
        if (ch==8220 || ch==8221 || ch=='\"') {
            newLine.appent("&quot;");
        }
        else if (ch=='<') {
            newLine.appent("&lt;");
        }
        else if (ch=='>') {
            newLine.appent("&gt;");
        }
        else if (ch=='\'') {
            newLine.appent("&#39;");
        }
        else {
            newLine.append(ch);
        }
    }
    return newLine.toString();
}
