为 <parameter>parser</parameter> XML 解析器设置处理指令（PI）处理函数。

<para>
|

处理指令有如下格式：
|
||
<programlisting role="xml">
|
||
<![CDATA[
|
||
<?target
|
||
data
|
||
?>
|
||
]]>
|
||
</programlisting>
|
||
</para>
|
||
<caution>
|
||
<para>
|
||
PHP 代码通过 <literal><?php</literal> 处理指令分隔。因此可以在 XML 文档中使用 PHP
|
||
代码。但是 PI 结束标记（<literal>?></literal>）不能是数据的一部分。如果 PI
|
||
结束标记存在于嵌入式 PHP 代码的一部分，则 PHP 代码的其余部分以及“真实的”PI 结束标记将会视为字符数据。
