Errors loading XML file with validation

I've searched on the ML archives and can't find what I'm looking, but I
might just be stupid and can't find it.

I'm using Jelly to load this file, but that list directed me here.  here's
what I'm getting:

328  [main] ERROR org.apache.commons.jelly.parser.XMLParser  - Parse Error
at line 2 column 247: cvc-elt.1: Cannot find the declaration of element
'x:action'.

	at com.npci.xportal.Test.main(Test.java:54)

This XML file validates in XMLSpy just fine.  Here's the root element
declarations I'm using:


<x:action
	xmlns="http://npci.com/xportal/1.0"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:x="http://npci.com/xportal/1.0"
	xsi:schemaLocation="-//http://npci.com/xportal/1.0//-
D:\projects\xportal-definitions\xsd\jdbc-handler.xsd">

Here's the code I'm using to parse with:

			StringWriter sw = new StringWriter();
			XMLSerializer ser = new XMLSerializer(sw, (new OutputFormat()));
			SAXParser parser = new SAXParser();
			parser.setFeature(
					"http://apache.org/xml/features/validation/schema", true);
			parser.setFeature(
					"http://xml.org/sax/features/validation", true);
			parser.setFeature(
					"http://xml.org/sax/features/namespaces", true);
			parser.setFeature(
					"http://xml.org/sax/features/namespace-prefixes", false);

			XMLParser jellyParser = new XMLParser(parser);
			XMLOutput jellyOutput = new XMLOutput(ser.asContentHandler());
			Script jellyScript = jellyParser

.parse("d:/projects/xportal-definitions/actions/sql/payroll/get_check_hdr.xm
l");
			jellyScript.compile();
			jellyScript.run((new JellyContext()), jellyOutput);

			System.out.println("[After]: " + sw.toString());

			ByteArrayInputStream bais = new ByteArrayInputStream(sw.toString()
					.getBytes());
			DefaultConfigurationBuilder configBuilder = new
DefaultConfigurationBuilder();
			Configuration config = configBuilder.build(bais);

			System.out.println("[Config]: "
					+ ConfigurationUtil.toString(config));

If I change the feature "http://xml.org/sax/features/namespace-prefixes" to
"false", then I get an error because the XML is corrupted to this:

<x:action
	schemaLocation="-//http://npci.com/xportal/handler/JDBC/1.0//-
file:///D:/projects/xportal-definitions/xsd/jdbc-handler.xsd"
="http://npci.com/xportal/handler/JDBC/1.0"
	xmlns="http://npci.com/xportal/handler/JDBC/1.0"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

Any help you could give me here would be MUCH appreciated...


Thanks!

Hi Simon,

That was the exact problem!  I had some invisible characters from my dataset creation process. 
Thank you very much!!!

Normally, this error message indicates that there is some non-xml
present before the xml starts.

I'm wondering if there are some "invisible" chars in your document and
the way you "chop up" the file is cleaning them out.

If you are using unix/linux, have you tried inspecting the file using
something like
  od -cx input.xml | more
to see *exactly* what chars your file starts with?

Regards,

Simon

Content is not allowed in prolog error when sax parsing large file

Posted by Duane Jung <du...@yahoo.com>.
Hi,

While parsing a large XML file (1000 items/56mb), I get the following error:

[Fatal Error] 1k_CIN.xml:2:1: Content is not allowed in prolog.

I've chopped this file up into smaller sets of items (50 items/1.5mb) and can parse those without
any problems.  Its only when I try to parse the larger file that I encounter the prolog error.

The prolog is the same in all of the files:
<?xml version="1.0" encoding="UTF-8"?>

I'm using xerces-2_6_2, parsing with Sax XMLReader.  I've tried passing in a system id and
inputsource to the parser -- both result in the prolog error with the larger file.  The smaller
files parse without any problems.

Does anyone have any ideas?

Thanks in advance, 
Duane

Re: Errors loading XML file with validation

Hello Jon,

If the target namespace of your schema is 
"http://npci.com/xportal/handler/JDBC/1.0" then you should specify that in 
the schemaLocation instead of 
"-//http://npci.com/xportal/handler/JDBC/1.0//-". Hope that helps.
