Hi!
I am trying to use Xerces to read the XML prolog in order to get the
file encoding/version.
Unfortunately, I could not get it to work (the getEncoding() method
returns ""). So I guess I must have missed something out despite the
fact that I have read the FAQ, the API, as well as previous posts:
<http://xerces.apache.org/xerces2-j/faq-sax.html#faq-6>
<http://www.nabble.com/Accessing-xml-and-doctype-declaration-via-SAX-td15992692.html#a16039477>
<http://java.sun.com/j2se/1.5.0/docs/api/org/xml/sax/ext/Locator2.html#getEncoding()
<http://java.sun.com/j2se/1.5.0/docs/api/org/xml/sax/ext/Locator2.html#getEncoding%28%29>>
So in an attempt to be as accurate as possible, here is a code sample:
private class CustomHandler extends DefaultHandler2 {
Locator2 myLocator = null;
public CustomHandler() {
super();
}
public void startDocument() {
log.debug("Start analysing the XML document");
}
public void startElement(String uri, String localName, String
qName, Attributes attributes){
String encoding = myLocator.getEncoding();
log.debug("encoding: " + encoding);
}
public void setDocumentLocator(Locator2 aLocator){
this.myLocator = aLocator;
super.setDocumentLocator(aLocator);
}
}
...
try{
//SAX Parser instantiation
SAXParserFactory factory =
SAXParserFactory.newInstance();
SAXParser parser = factory.newSAXParser();
//Handler + Locator instantiation
CustomHandler myHandler = new CustomHandler();
Locator2 myLocator = new Locator2Impl();
myHandler.setDocumentLocator(myLocator);
parser.parse(aFile, myHandler);
}catch(Throwable e){
log.debug("Error!", e);
}
For information, the XML file I am working with looks like:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<root>
<tag1></tag1>
<tag2></tag2>
...
</root>
I hope someone can help.
Thanks in advance,
