| <H4 class="dtH4">Thread Safety</H4> |
| <P>Public static (<b>Shared</b> in Visual Basic) members of this type are |
| safe for multithreaded operations. Instance members are <b>not</b> guaranteed to be |
| thread-safe.</P> |
| <h4 class="dtH4">Remarks</h4> |
| <p> The output of the <b>XmlLayout</b> consists of a series of log4net: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> |
| <p> For example, if <code>abc</code> is the name of the file where the <b>XmlLayout</b> output goes, then a well-formed XML file would be: </p> |
| <pre class="code"><span class="lang">[XML] |
| </span> <?xml version="1.0" ?> |
| |
| <!DOCTYPE log4net:events SYSTEM "log4net-events.dtd" [<!ENTITY data SYSTEM "abc">]> |
| |
| <log4net:events version="1.2" xmlns:log4net="http://logging.apache.org/log4net/schemas/log4net-events-1.2> |
| &data; |
| </log4net:events> |
| </pre> |
| <p> This approach enforces the independence of the <b>XmlLayout</b> and the appender where it is embedded. </p> |
| <p> The <code>version</code> attribute helps components to correctly interpret output generated by <b>XmlLayout</b>. The value of this attribute should be "1.2" for release 1.2 and later. </p> |
| <p> Alternatively the <code>Header</code> and <code>Footer</code> properties can be configured to output the correct XML header, open tag and close tag. When setting the <code>Header</code> and <code>Footer</code> properties it is essential that the underlying data store not be appendable otherwise the data will become invalid XML. </p> |
