uploading & processing a xml file

[crojar]

Ok this might be a stoopid question, but here I go. I have a html that will upload and process an xml string successfully.

html code that works:

<FORM action="http://xxx.xxx.com/xxx/dispatcher" method=post>
<INPUT TYPE=text size=220 name=com.xxx.xxx.xxx.REQUEST_PLACEHOLDER value="<!DOCTY....

However, I want to upload and process an xml file to the same server. I tried 3 different ways: curl, html form, and vba

Each way I connect to the server but the requrest is not successful

1) C:\temp\curl>curl -d@auth_simple_rqstII.xml -o myresp.xml "http://xxx.xxx.com/xxx/dispatcher"

server log:

[Fatal Error] :1:1: Premature end of file.
org.xml.sax.SAXParseException: Premature end of file.


2) Html Form

<form enctype="multipart/form-data" method="post" action="http://xxx.xxx.com/xxx/dispatcher">
Enter filename to upload: <input type="file" name="xxx.xxx.xxx.xxx.REQUEST_PLACEHOLDER"><br>
<input type="submit">

server log

[Fatal Error] :1:1: Content is not allowed in prolog.
org.xml.sax.SAXParseException: Content is not allowed in prolog.

3) VBA request

server log: [Fatal Error] :1:1: Premature end of file.
org.xml.sax.SAXParseException: Premature end of file.


Do I need to modify the xml file ( I can load it in sucessfully in MS XML notepad)?

Do I need to change the HTTP request?

Does anyone has any idea about this problem. I runs into the same situation.

I'm not a web developer ... but concerning error description "org.xml.sax.SAXParseException: Content is not allowed in prolog" I can guess that feedback from HTTP request is enclosed in HTML envelope (it seams to be logical since it is HTML request :rolleyes: ). So before U start processing XML U should somehow strip of that envelope.



Best regards,

hi I do not know if this thread but I would love for somebody to look at the following:
( for those of you who want to actually try the code, it can be downloaded at http://www.people.virginia.edu/~gsd4x/DigitalLibrary.zip)
here is the xml file:

<?xml version = "1.0" encoding= "UTF-8"?>
<library>
<item>
<type>
1
</type>
<id>
266
</id>
<author>
authors_name
</author>
<title>
item's title
</title>
<date>
MONTH/DAY/YEAR
</date>
<issue>
235
</issue>
<edition>
2nd_Edition
</edition>
<publisher>
Computer_Arts
</publisher>
<keyword>
KEY WORD
</keyword>
<description>

</description>
</item>
</library>


and here is the code to process it:

SAXParserFactory factory = SAXParserFactory.newInstance();
factory.setValidating(false);
try {
SAXParser parser = factory.newSAXParser();
parser.parse( new File(libraryfile), libHandler );
} catch (ParserConfigurationException ex) {
ex.printStackTrace();
} catch (SAXException ex) {
ex.printStackTrace();
}


I get the same type of error mentioned:

Sounds like your xml is not well formed, or the parser is overparticular.

Try removing the spaces:
Change <?xml version = "1.0" encoding= "UTF-8"?>
to
<?xml version="1.0" encoding="UTF-8"?>

I have tried it and I still get the same answer.

[jkmyoung]

1. You need a space between item and ( in lib.dtd
2. Have you tried using the DefaultHandler class as opposed to your LibraryHandler? Do you still get the same parsing errors?
