The output of the XMLLayout consists of a series of log4j:event
elements. It does not output a
complete well-formed XML file. The output is designed to be
included as an <em>external entity</em> in a separate file to form
a correct XML file.
<p>For example, if <code>abc</code> is the name of the file where
the XMLLayout ouput goes, then a well-formed XML file would be:
<code>
<?xml version="1.0" ?>
<!DOCTYPE log4j:eventSet [<!ENTITY data SYSTEM "abc">]>
<log4j:eventSet version="1.2" xmlns:log4j="http://jakarta.apache.org/log4j/">
