| | | Reading files without a DTD | Reading files without a DTD 2006-06-20 - By Dmitriy Viner
Back
I'm trying to traverse a well-formed files without a dtd. I'm not validating
any files. I have it explicitly turned off. Files between 10k and 10M go
through without any problems. However once the file becomes 20M I'm getting
this exception from exactly the same code that reads smaller files without any
problems:
parser = new SAXBuilder();
document = parser.build("file.xml");
String:org.jdom.input.JDOMParseException: Error on line 1 of document file://
/C:/samples/file.xml: cvc-elt.1: Cannot find the declaration of element 'astg'.
Message:Error on line 1 of document file:///C:/samples/file.xml: cvc-elt.1:
Cannot find the declaration of element 'astg'.
Java Result: 1
File file.xml is just well formed file with a root tag astg and structure
that looks exactly like this:
<astg>
<element1/> <element2/> ......
</astg>
If I add a DOCTYPE statement and a dummy dtd the file goes right through.
<?xml version="1.0" encoding="UTF-8 (See http://UTF-8.ora-code.com)"?>
<!DOCTYPE astg SYSTEM "vlr.dtd" [
]>
<astg>
<element1/> <element2/> ......
</astg>
astg.dtd
<?aptxml version="1.0" encoding="utf-8 (See http://utf-8.ora-code.com)"?>
<!ELEMENT astg (#PCDATA)>
Do you guys have any idea what is possible cause of the exception?
Regards,
DV
