I think you will find that if you actually use valid XML, it will work 
just fine. Openbox will still replace the tilde with your homedir though, 
since that takes place after the XML parsing.

PS &#x7E;
&tilde; is not a predefined xml reference, quoth wikipedia:

Special characters can be represented either using entity references, or 
by means of numeric character references. An example of a numeric 
character reference is "&#x20AC;", which refers to the Euro symbol by 
means of its Unicode codepoint in hexadecimal.

An entity reference is a placeholder that represents that entity. It 
consists of the entity's name preceded by an ampersand ("&") and followed 
by a semicolon (";"). XML has five predeclared entities:

     * &amp; (& or "ampersand")
     * &lt; (< or "less than")
     * &gt; (> or "greater than")
     * &apos; (' or "apostrophe")
     * &quot; (" or "quotation mark")
