API doesn't return valid XML

Hello!

I have a question regarding to the fetching of test-cases using the TestLink API.

I currently use QF-Test and it has the ability to create empty test suites out of test-cases fetched from TestLink.

We try to fetch the Testlink projects, but we get an annoying problem: The defined Testlink projects cannot be fetched, the following error message occurs:
The processing instruction target matching "[xX][mM][lL]" is not allowed.

I used the provided class “TestlinkAPIXMLRPCClient“ of TestLink library and added necessary value for DEV_KEY and SERVER_URL. I compiled the java file and promptly got an error message (please look at the output (CODE)).

Code: Select all

[Fatal Error] :1:7: The processing instruction target matching "[xX][mM][lL]" is not allowed.
org.apache.xmlrpc.client.XmlRpcClientException: Failed to parse servers response: The processing instruction target matching "[xX][mM][lL]" is not allowed.

We found out that fetching XML files from TestLink we got corrupted files. We added a print sequence to the fetched data. At the end, we realized that there is a space before the „<?xml version="1.0"?>“.

We currently use the TestLink version 1.9.7 and Apache/2.2.16 (Debian).

Maybe someone else there had this problem and can help me

Thank you for any answers!

Sincere regards,
