XML seralization & hexadecimal values

I'm getting '', hexadecimal value 0x02, is an invalid character when I'm
deseralizing XML from a 3rd party XML gateway. How do I get rid of these
hexadecimal values before I deserialize?

Cheers

Hi Damon,

How does your xml file serialized?
Is it also serialized by this 3rd part component?
If it is, why it can not deserialize, I think it may be the problem of the
3rd part component.

As a workaround, may be you can use IO operation to open this xml
file and get all the content, then delete the '' characters store it as a
new xml file.

You can try to deserialize this new file to see if it works.

Hope this helps,
Best regards,

I've found out the reason why these hexadecimal values are coming up in the
XML request. It is because the request is GSM encoded as its an XML gateway
for sending and receiving SMS messages.

This means that letters such as a-z come through fine but characters such as
$ which is 2 in the GSM character set throws the below error.

What I'm not sure on is how to do the conversion to and from GSM. I'm
getting the response back from the other server using a StreamReader which
defaults to UTF8 encoding.

In order to do this conversion will I need to create my own encoding object
and then change the encoding type on the StreamReader to be something like
GSMEncoding or is there another way?

Cheers

Damon

Hello Damon,

Thanks for the detailed description.

Based on my understanding, now the XML gateway sends and receiveds the data
by usign GSM encoding. So the '' is '$' after the encoding. Please post
here if I have misunderstood anything.

If the GSM character set doesn't inlcude '$', I think we need to transfer
it manually. That is to say, we need to create a customized class to encode
the xml string before transferring it to GSM gateway. Then decoding work
should also be done by ourselves.

We are not sure of if there is any setting in GSM gateway side to avoid it.
You need to post in their group for more information. It is very possible
that they have existing encoding class already.

Hope that helps.

Hi Yanhong,

You are correct about how the GSM encoding works.

I have created a GSMEncoding object however from what I have found the
message is not always GSM encoded. I need to perform some more tests to try
and find out what is happening and the service providers is not sure
themselves.

I have a test system being set-up in the next couple of days so I will reply
with my findings then.

Cheers

Damon
