## LoggerLayoutXml

`LoggerLayoutXml` formats the messages as an XML document.

### Parameters

The following parameters are available:

Parameter | Type | Required | Default | Description
--- | --- | --- | --- | ---
locationInfo | boolean | No | true | If set to true, adds the file name and line number at which the log statement originated.
log4jNamespace | boolean | No | false | If set to true then log4j XML namespace will be used instead of the log4php namespace. This can be usefull when using log viewers which can only parse the log4j namespace such as Apache Chainsaw.

### Examples

#### Default configuration example

The default configuration of `LoggerLayoutXml` will use the log4php XML namespace and include the location information.

Configuration file:

- XML
- PHP

    <configuration xmlns="http://logging.apache.org/log4php/">
        <appender name="default" class="LoggerAppenderEcho">
            <layout class="LoggerLayoutXml" />
        </appender>
        <root>
            <appender_ref ref="default" />
        </root>
    </configuration>

    array(
        'appenders' => array(
            'default' => array(
                'class' => 'LoggerAppenderEcho',
                'layout' => array(
                    'class' => 'LoggerLayoutXml',
                )
            )
        ),
        'rootLogger' => array(
            'appenders' => array('default')
        ),
    )

Running the following code:

    Logger::configure("config.xml");
    $logger = Logger::getLogger('myLogger');
    $logger->info("Lorem ipsum dolor sit amet, consectetur adipiscing elit.");
    $logger->debug("Donec a diam lectus.");
    $logger->warn("Sed sit amet ipsum mauris.");

Produces the following output:

    <log4php:eventSet xmlns:log4php="http://logging.apache.org/log4php/" version="0.3" includesLocationInfo="true">

    <log4php:event logger="myLogger" level="INFO" thread="4464" timestamp="1317215164482">
    <log4php:message><![CDATA[Lorem ipsum dolor sit amet, consectetur adipiscing elit.]]></log4php:message>
    <log4php:locationInfo class="main" file="D:\Temp\log4php\layout_pattern.php" line="5" method="main" />
    </log4php:event>

    <log4php:event logger="myLogger" level="DEBUG" thread="4464" timestamp="1317215164513">
    <log4php:message><![CDATA[Donec a diam lectus.]]></log4php:message>
    <log4php:locationInfo class="main" file="D:\Temp\log4php\layout_pattern.php" line="6" method="main" />
    </log4php:event>

    <log4php:event logger="myLogger" level="WARN" thread="4464" timestamp="1317215164514">
    <log4php:message><![CDATA[Sed sit amet ipsum mauris.]]></log4php:message>
    <log4php:locationInfo class="main" file="D:\Temp\log4php\layout_pattern.php" line="7" method="main" />
    </log4php:event>

    </log4php:eventSet>

#### Overriding default options

This example show how to configure `LoggerLayoutXml` to exclude the location information and use the log4j XML namespace.

Configuration file:

    <configuration xmlns="http://logging.apache.org/log4php/">
        <appender name="default" class="LoggerAppenderEcho">
            <layout class="LoggerLayoutXml">
            	<param name="locationInfo" value="false" />
            	<param name="log4jNamespace" value="true" />
            </layout>
        </appender>
        <root>
            <appender_ref ref="default" />
        </root>
    </configuration>

Using this configuration will produce the following output:

    <log4j:eventSet xmlns:log4j="http://jakarta.apache.org/log4j/" version="0.3" includesLocationInfo="false">
    <log4j:event logger="myLogger" level="INFO" thread="3156" timestamp="1317216571470">
    <log4j:message><![CDATA[Lorem ipsum dolor sit amet, consectetur adipiscing elit.]]></log4j:message>
    </log4j:event>

    <log4j:event logger="myLogger" level="DEBUG" thread="3156" timestamp="1317216571471">
    <log4j:message><![CDATA[Donec a diam lectus.]]></log4j:message>
    </log4j:event>

    <log4j:event logger="myLogger" level="WARN" thread="3156" timestamp="1317216571471">
    <log4j:message><![CDATA[Sed sit amet ipsum mauris.]]></log4j:message>
    </log4j:event>

    </log4j:eventSet>
