event
elements as defined in the log4j.dtd.
If you configure complete="true"
, the appender outputs a well-formed XML document where the default namespace
is the log4j namespace "http://logging.apache.org/log4j/2.0/events". By default, with complete="false"
, you should
include the output as an external entity in a separate file to form a well-formed XML document.
If complete="false"
, the appender does not write the XML processing instruction and the root element.
Appenders using this layout should have their charset
set to UTF-8
or UTF-16
, otherwise
events containing non-ASCII characters could result in corrupted log files.
By default, the XML layout is not compact (compact = not "pretty") with compact="false"
, which means the
appender uses end-of-line characters and indents lines to format the XML. If compact="true"
, then no
end-of-line or indentation is used. Message content may contain, of course, end-of-lines.
This property allows addition of custom fields into generated JSON.
<XmlLayout><KeyValuePair key="foo" value="bar"/></XmlLayout>
inserts <foo>bar</foo>
directly
into XML output. Supports Lookup expressions.
