Strange!! Unexpected end of file while parsing Name has occurred

[Anup Daware]

Hi Group,

I am facing a strange problem here:
I am trying to read xml response from a servlet using XmlTextWriter.
I am able to read the read half of the xml and suddenly an exception:
“Unexpected end of file while parsing Name has occurred” is being
thrown.

Following is the part o xml I am trying to read:
<CHECK_ITEM_OUT>
<ITEM id="">
<!-- id = [material] -->
<ITM_NUMBER>1</ITM_NUMBER>
<MATERIAL>001</MATERIAL>
<DEALER_CODE>DEL_One</DEALER_CODE>
<BRAND>Bridgestone</BRAND>
<HIERARCHY>HAR001</HIERARCHY>
<NET_PRICE>123.12</NET_PRICE>
<CURRENCY>EURO</CURRENCY>
</ITEM>
<ITEM id="">
<!-- id = [material] -->
<ITM_NUMBER>2</ITM_NUMBER>
<MATERIAL>002</MATERIAL>
<DEALER_CODE>DEL_Two</DEALER_CODE>
<BRAND>Firestone</BRAND>
<HIERARCHY>HAR002</HIERARCHY>
<NET_PRICE>453.12</NET_PRICE>
<CURRENCY>EURO</CURRENCY>
</ITEM>
<ITEM id="">
<!-- id = [material] -->
<ITM_NUMBER>3</ITM_NUMBER>
<MATERIAL>003</MATERIAL>
<DEALER_CODE />
<BRAND>FIRESTONE</BRAND>
<HIERARCHY>HAR001</HIERARCHY>
<NET_PRICE>24.12</NET_PRICE>
<CURRENCY>EURO</CURRENCY>
</ITEM>
</CHECK_ITEM_OUT>

When I am trying to read the <BRAND>FIRESTONE</BRAND> (In Third item
in the list), I am getting the “Unexpected end of file while parsing
Name has occurred” exception. I am able to read the values from
<BRAND> element for first two elements.
Following is the code I am using for reading the xml.

case "BRAND":
if (!xmlTextReader.IsEmptyElement)
productInfo.Brand =
xmlTextReader.ReadElementContentAsString();
break;

I also have searched net for this problem but I found nothing useful

Please let me know if I am doing something wrong or missing on
something.

Thanks,

Hi Group,

The problem is solved :)

Following lines were creating the problem:

StreamWriter streamWriter = new StreamWriter(responseStream);

streamWriter.Write(responseXml); //responseXml is a string

The the default buffer of StreamWriter is 4kb and the string
responseXml is more than that, thus only a portion of my xml was being
used by XmlTextWriter which is using responseStream: And that was the
reason of Unexpected end of file while parsing Name has occurred
exception.

Solution:

Rather than using the the StreamWriter, I directly used the
responseStream.Write; for this I converted the string to byte array.
Following is the code for it.

String responseXml = GetResponseStream(uri,
searchRequestXML);
System.Text.UTF8Encoding ob = new UTF8Encoding();
byte[] arr2 = ob.GetBytes(responseXml);
responseStream.Write(arr2,0,arr2.Length);
responseStream.Seek(0, SeekOrigin.Begin);
XmlTextReader xmlTextReader = new
XmlTextReader(responseStream)

Well the conclusion is StreamWriter has a default size of 4KB which is
not increased dynamically, and this is really unexpected.

The real problem is that you didn't call streamwriter.flush after the
write. There's nothing wrong with your original code.

Alternately you can call close, which should flush. I think that's
preferred as its in all the msdn examples.
