testng: TestNG XML not valid with DTD @ http://testng.org/testng-1.0.dtd

Please see stackoverflow link here: http://stackoverflow.com/questions/42772424/testng-xml-not-valid

I am getting issues with the XML not meeting the DTD.

TestNG Version

Tried on 6.11 and 6.9.11

Expected behavior

XML should be valid with DTD.

Actual behavior

Getting the error: 1: 3 The markup declarations contained or pointed to by the document type declaration must be well-formed.

Is the issue reproductible on runner?

• Shell
• Maven
• Gradle
• Ant
• Eclipse
• IntelliJ
• NetBeans

Test case sample

I have some generated TestNG XMLs that worked for a long time, but recently they are invalid when I run them through Java’s SAXParser and through http://www.xmlvalidation.com/

Example generated XML:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite thread-count="1" verbose="2" name="TestNG Forum" parallel="tests">
  <test name="TestNG Test0" preserve-order="false">
    <parameter name="device" value="58f56054954b6b3e323a3405fc49023eb1569a98"/>
    <packages>
      <package name="output"/>
    </packages>
  </test> <!-- TestNG Test0 -->
</suite> <!-- TestNG Forum -->

Example XML from TestNG’s site @ http://testng.org/doc/documentation-main.html

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >

<suite name="Suite1" verbose="1" >
  <test name="Nopackage" >
    <classes>
       <class name="NoPackageTest" />
    </classes>
  </test>

  <test name="Regression1">
    <classes>
      <class name="test.sample.ParameterSample"/>
      <class name="test.sample.ParameterTest"/>
    </classes>
  </test>
</suite>

EDIT:

SAXParser error:
