<p>Uses PHP’s output buffering to buffer XML-RPC responses and strip superfluous whitespace.</p>
<p>Plugins, themes, and any other files executed during the WordPress load process can unintentionally emit whitespace,<br />
such as by including a newline character after an explicit closing “?>” PHP tag instead of letting PHP auto-close the<br />
file.</p>


XML-RPC De-whitespacer

Removes leading and trailing whitespace from XML-RPC responses that can break some XML-RPC clients.
