G'day filipebean,

There's a number of special characters that may need to be escaped in XML content: "<" to "&lt;"; ">" to "&gt;"; and "&" to "&amp;" (see XML Predefined Entities). So, 

<rule>['^(<xyz>)']</rule>

[download]

would become

<rule>['^(&lt;xyz&gt;)']</rule>

[download]

Given the readability issues, it might be better to use CDATA blocks (see XML CDATA Sections) to escape the entire regex, e.g. 

<rule><![CDATA[['^(<xyz>)']]]></rule>

[download]

[Note: I haven't investigated how XML::Simple interacts with these constructs.]
