Re: [dom4j-user] Error in prolog?

[Ben Munat]

I seem to remember seeing that error back when Tomcat had some problems with the version 
of Xalan it was using (you had to put a different version in the "endorsed" dir). So, I 
wonder if changing the underlying SAX parser would help. See the SAXReader javadoc about 
how to do that.

If it does turn out to be a bad parser, you might check to see if you have a system 
classpath set and if there are any parsers on there. Er, or actually, the javadocs suggest 
that it's a system property that determines which parser is used...

good luck,

Ben

==================

I keep getting

org.dom4j.DocumentException: Error on line 1 of document  : Content is 
not allowed in prolog. Nested exception: Content is not allowed in prolog.

I get the same (more or less) using XOM/NUX.

I tried using XPP3Reader as well with the following result:

org.xmlpull.v1.XmlPullParserException: only whitespace content allowed 
before start tag and not \uef (position: START_DOCUMENT seen \uef... @1:1)
        at org.xmlpull.mxp1.MXParser.parseProlog(MXParser.java:1475)
        at org.xmlpull.mxp1.MXParser.nextImpl(MXParser.java:1351)
....

I have tried using
<?xml version="1.0"?>
and
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
and also to skip the prolog altogether.

The file should be UTF-8 (according to UltraEdit and Firefox it is).

I am invoking using this code:
SAXReader saxReader = new SAXReader();
saxReader.addHandler("/epg/genres/genre",
        new CategoryHandler(tvGuide, languageCode));
saxReader.addHandler("/epg/channels/channel",
        new ChannelHandler(tvGuide, channelMap, languageCode));
saxReader.read(content);

content is an InputStream coming from a file (Windows)

I built the code and tested using small files (it worked then) and the 
error occurs now when I tried to feed it with real data (about 5 
megabytes, file generated by someone else).

The file opens fine in IE and Firefox and I've also tried using another 
parser (REXML in Ruby) which also works fine.

Any ideas?
