Msxml2.ServerXMLHTTP.4.0 + &

| Hello,
I have a process that has been sending an xml file to a different web server using Msxml2.ServerXMLHTTP.4.0 and I just recently came into a problem.
This is how it works:
password=Request.Form("password")
password=Request.Form("password")
xmlData = Request.Form("xmlData")
Set xmlConnection = Server.CreateObject("Msxml2.ServerXMLHTTP.4.0")
xmlConnection.Open "POST", sendServer, False
xmlConnection.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
xmlConnection.Send "username="+username+"&username="+username+"&xml="+xmlData
This works just fine until the xml has an & sign in it, from what I gather when I type this line:
xmlConnection.Send "username="+username+"&username="+username+"&xml="+xmlData
The & character in the xml breaks the xml variable apart. If my xml looked like this <basic>george & wallace</basic>
The url string would look like this:
server?username=user&password=pass&xml=<basic>george & wallace</basic>
so the server would receive the following variables:
username=user
password=password
xml = <basic>george
wallace=</basic>
Does this make sense? Is there a way I can get around this?

| You have to encode the ampersand as & or use the unicode number (0026 - not sure about the
actual format for this) or the numeric format & (which I prefer).
The obvious problem is handling how this is output to the resultant XML / HTML / text when using an
XSL transform - a big topic.
Note that when DOM methods are used to put the value into an XML document then the XML parser
automagically puts the encoded version on for you - getting it out again is another matter entirely.

| Hi Chris, thanks for the reply.
Let me try to rephrase my question.
I am trying to send 3 variables using Msxml2.ServerXMLHTTP.4.0
The first variable is the username, the second the password, and the last variable is a block of xml.
This process has been working fine, until I came across the & symbol.
I have many different systems running that are translating xml, so whenever I have this problem it is just a matter of changing the character from & to & (I'm not sure how this formatting will display in the newsgroups so I format the & sign to & a m
p ;)
This usually does the trick. In this case it does not seem to have any effect and I still get an error from the web site I post the xml to. The error always says the same thing; there is a problem with line X (where X is the line with the & symbol).
From what I have gathered the problem isn't how I am sending the & character, because I know I am sending it properly formatted. But from the way Msxml2 posts my information.
This line:
xmlConnection.Send "user="+username+"&pass="+password+"&xml="+xmlData
In this line I am just connecting strings together. Could this be the problem?
Let's say my "username" variable was joe&bard
That line above would translate to:
xmlConnection.Send "user=joe&bard"&pass="+password+"&xml="+xmlData
And if my password value was pass2, and the xmlData was <xml></xml>
It would be fully translated as:
xmlConnection.Send "user=joe&bard&pass=pass2&xml=<xml></xml>"
So when the web server on the other side tries to get the value of "user" they would only get "bard" as a response. Correct?
Even if the & sign was changed to & It would look like this:
xmlConnection.Send "user=joe&bard&pass=pass2&xml=<xml></xml>"
or (depending on newsgroup formatting)
xmlConnection.Send "user=joe&bard&pass=pass2&xml=<xml></xml>"
And (in either example) when the person requested the value of "user" they would still only get "joe". That's because the & sign is forcing that variable to end.
The same with the xml, the & sign, no matter if it is formatted or not (&, &, &) is forcing that variable to end.
This is what I am thinking is happening to my xml when I send it. What I need to know is if there is a way to rewrite my xmlConnection.Send line so it does not have all of the variables concatenated on a single string. Or a way to eliminate this ampersand
problem?
