> If you use something like ch.qos.logback.classic.log4j.XMLLayout you can
> create xml based log files. However the problem is that it does not add root
> element making the resulting file not well-formed.
> You can activate the logging in your logback.xml like
> <appender name="FAILS" class="ch.qos.logback.core.FileAppender">
> <file>${crawler.log.error}</file>
> <append>false</append>
> <encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">
> <layout class="ch.qos.logback.classic.log4j.XMLLayout">
> <locationInfo>true</locationInfo>
> </layout>
> </encoder>
> </appender>
> The implemented solution has the following configuration in spring:
> <bean name="generator:log4j"
> class="org.apache.cocoon.optional.pipeline.components.sax.generator.AddRootElementGenerator"
> scope="prototype">
> <property name="encoding" value="UTF-8"/>
> <property name="localName" value="events"/>
> <property name="prefix" value="log4j"/>
> <property name="namespace" value="http://jakarta.apache.org/log4j/"/>
> </bean>
> and later parse the file that the appender gives like:
> <map:pipeline>
> <map:match pattern="errorLogs">
> <map:generate src="${crawler.log.error}" type="log4j"/>
> <map:serialize type="xml" />
> </map:match>
> </map:pipeline>
> which will result in something like:
> <?xml version="1.0" encoding="UTF-8"?>
> <log4j:events xmlns:log4j="http://jakarta.apache.org/log4j/";>
> <log4j:event logger="org.apache.droids.exception.ExceptionHandler"
> timestamp="1361325224196" level="ERROR" thread="main">
> <log4j:message><![CDATA[org.apache.droids.core.DroidsException:
> org.apache.droids.core.DroidsException:
> org.apache.droids.core.DroidsException:
> org.apache.http.client.HttpResponseException: Internal Server Error
> http://localhost:8888/xxx/details/xxx]]>
> </log4j:message>
> <log4j:locationInfo class="org.apache.droids.exception.ExceptionHandler"
> method="handleException" file="ExceptionHandler.java" line="23"/>
> </log4j:event>
> </log4j:events>
