XML API validation: Parsing Error: Content is not allowed in prolog

jeanlaforest1 · ‎03-19-2015

I am sending the following xml message to https://mywebsite.webex.com/WBXService/XMLService

<?xml version="1.0" encoding="UTF-8"?>

<serv:message xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

<webExID>myuserid</webExID>

<password>mypassword</password>

<siteID>mysite</siteID>

<partnerID>mypartnerid</partnerID>

<email>myemail</email>

</securityContext>

</header>

<body>

</listControl>

<order>

<orderBy>CONFNAME</orderBy>

<orderBy>STARTTIME</orderBy>

</order>

</bodyContent>

</body>

</serv:message>

I get the following response.

<serv:message xmlns:serv=http://www.webex.com/schemas/2002/06/service xmlns:com=http://www.webex.com/schemas/2002/06/common><serv:header><serv:response><serv:result>FAILURE</serv:result>

<serv:reason>validation: Parsing Error : Content is not allowed in prolog.

Line : 1

Column : 1

</serv:reason>

<serv:gsbStatus>PRIMARY</serv:gsbStatus>

<serv:exceptionID>999999</serv:exceptionID>

</serv:response>

</serv:header>

<serv:body><serv:bodyContent></serv:body>

</serv:message>

This must be a rookie mistake. Can you help?

Thanks

That error is almost always due to whitespace or otherwise 'invisible' characters at the very top of the XML document, i.e. prior to the 'prologue' <?xml version="1.0" encoding="UTF-8"?>

If there is not an obvious space or blank line before the prologue, then the other common problem can be due to an invisible 'byte order mark' (BOM) Byte order mark - Wikipedia, the free encyclopedia

at the beginning of the XML portion. This can occur if you've saved the XML in a windows app like Notepad.

Thanks much. I had read that before but did not believe it applied to me

since I was not using Notepad to generate the string.

I was building the xml string in the code. Anyway I finally replace that

method with the proper XmlTextWriter class and that solved my issue.

Thanks again for your help.
