I have a number of carriage returns and tabs within an xml element. When I take that element I would like it to transform to html in which I am then displaying within a JEditorPane. However, when I do this it is one long string. I have tried the xml:space="preserve" within that element and this still is not working.
Here is part of the xml with the carriage return line feeds. The element that I am talking about is called pseudocode. You can see it is displayed correctly below.
Design Document XML : <?xml version="1.0" encoding="ISO-8859-1"?><design-doc><title-page><title>Testing Document</title><class-prepared-for>Lloyd</class-prepared-for><authors>Ben Garbers</authors><date-created>September 23, 2004</date-created></title-page><introduction text="This is the introduction. This is the introduction."/><class-definitions><class-definition class-name="ClassOne" visibility="public" class-complexity="not complex"><global-variables><variable visibility="public" name="VariableOne" object="String" comments="This is a String."/><variable visibility="public" name="VariableTwo" object="Integer" comments="This is an Integer."/></global-variables><methods><method name="MethodOne" synopsis="This will do some things." purpose="public" visibility="public"><input-parms><variable visibility="null" name="firstName" object="String" comments="null"/></input-parms><output-parms><variable visibility="null" name="lastName" object="String" comments="null"/></output-parms><local-variables><variable visibility="null" name="age" object="int" comments="null"/></local-variables><pseudocode xml:space="preserve">/* Ensure that player name exist in the system*/
if (player =null)
NullPlayerException;
if (NOT (isPlayerNameExist(player)))
throw PlayerNameNotExistException;
/* Ensure player name exist in the team already*/
i ? 1;
while (i <= length(mPlayers)) {
if (mPlayers
.mPlayerName != playerName)
throw PlayerNameNotExistInTeamException;
}
this.mPlayers ? this.mPlayers - player;</pseudocode>
However, when I do the transformation I get the following with the pseudocode:
/* Ensure that player name exist in the system*/if (player =null) NullPlayerException; if (NOT (isPlayerNameExist(player))) throw PlayerNameNotExistException; /* Ensure player name exist in the team already*/ i ? 1; while (i <= length(mPlayers)) { if (mPlayers[i].mPlayerName != playerName) throw PlayerNameNotExistInTeamException;}this.mPlayers ? this.mPlayers - player;
It looks like it adds some spaces but no carriage returns or line feeds.
My transformation code is the following:
public ParseFile(String xmlString) {
try {
//Here we will load the correct style sheet for the message
//that will be formatted.
String urlString = "DesignDocument.xsl";
URL url = this.getClass().getResource(urlString);
System.out.println("URL to style sheet = " + url.toString());
String styleSheetName = url.getFile();
System.out.println("Style sheet name : " + styleSheetName);
InputStream styleSheetInputStream = this.getClass().getResourceAsStream(urlString);
//We will than load our SAXParerFactory and parse the message.
SAXParserFactory SPFactory = SAXParserFactory.newInstance();
SPFactory.setValidating(true);
SAXParser sp = SPFactory.newSAXParser();
XMLReader sax2parser = sp.getXMLReader();
//NO Validation done on for this because we do NOT have a DTD.
sax2parser.setFeature(
"http://xml.org/sax/features/validation",
false);
sax2parser.setContentHandler(new FileContentHandler());
//we create a character array of the length of the xml message String
char[] messageCharacterArray =
new char[xmlString.length()];
// we then put the xml string into the character array.
messageCharacterArray = xmlString.toCharArray();
// after this ew end up creating a CharArrayReader that will be used by the Sax
// parser to parse the xml.
CharArrayReader xmlCharArrayReader =
new CharArrayReader(messageCharacterArray);
// we put the xml character array within the Input Source which will then be parsed
// by the Sax2 parser.
InputSource in = new InputSource(xmlCharArrayReader);
// Use a Transformer for outputting the message into our formatted xml using
// the stylesheet defined up in a messages own sxl stylesheet file.
TransformerFactory tFactory = TransformerFactory.newInstance();
tFactory.setURIResolver(new BasicURIResolver());
StreamSource stylesource = new StreamSource(styleSheetInputStream);
Transformer transformer = tFactory.newTransformer(stylesource);
// transformer.setOutputProperty(OutputKeys.INDENT, "yes");
// transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");
// Properties properties = new Properties();
// properties.setProperty("indent", "yes");
// properties.setProperty("{http://xml.apache.org/xslt}indent-amount", "2");
// transformer.setOutputProperties(properties);
// We will use a ByteArrayOutputStream to put our transformed xml.
ByteArrayOutputStream bos = new ByteArrayOutputStream();
StreamResult result = new StreamResult(bos);
SAXSource source = new SAXSource(in);
transformer.transform(source, result);
String s = bos.toString();
StringBuffer sb = new StringBuffer();
//This will make sure the Version Line is not shown.
BufferedReader br = new BufferedReader(new StringReader(s));
String line = "";
while ((line = br.readLine()) != null) {
sb.append(line);
}
bos.close();
br.close();
formattedXmlString = sb.toString();
System.out.println("--------------------------------");
System.out.println(formattedXmlString);
System.out.println("--------------------------------");
} catch (Exception e) {
e.printStackTrace();
}
}
I have been searching and trying to figure this out forever. Any help would be greatly appreciated. Bottom line is that I want carriage returns and tabs to work when transferring from the xml to xsl.
