Hi jidanni,
thanks for reporting.
Well, the XML file is correct, i.e., the file is 'well-formed'. Alas, it has
no DTD or XML Schema attached against which one could test its validity. So
this is why validome.org can not verify and reports an error. [1]
A good command line tool to use for that purpose is xmllint(1) from the libxml2
GNOME XML library.
$ xmllint /usr/share/doc/basex/examples/input.xml
<?xml version="1.0" encoding="UTF-8"?>
<html>
<!-- Header -->
<head id="0">
<title>XML</title>
</head>
<!-- Body -->
<body id="1" bgcolor="#FFFFFF" text="#000000" link="#0000CC">
<h1>Databases & XML</h1>
<div align="right">
<b>Assignments</b>
<ul>
<li>Exercise 1</li>
<li>Exercise 2</li>
</ul>
</div>
</body>
<?pi bogus?>
</html>
---> XML file is well-formed
Since we do not have a Document Type Definition (DTD) the following will fail:
$ xmllint --valid /usr/share/doc/basex/examples/input.xml
/usr/share/doc/basex/examples/input.xml:2: validity error : Validation failed:
no DTD found !
I'll think about including a simple DTD in the next release.
Thanks,
Alex
