Hey Rob,
In my lib I have a function that protects all regexp special characters.
Maybe a bit too much heavy machinery for what it does but it works ;-)
I gladly receive improvements.
declare function route:re-escape($string as xs:string)
as xs:string {
let $regexp-chars := ('.','*','+','|','?','(',')','[',']','{','}','^')
return
(: Note that '\' and '$' in the fold caused invalid pattern errors
therefore put them in separate replace :)
fold-left(
$regexp-chars,
replace(replace($string, '\\', '\\\\'), '\$', '\\\$'),
function($a, $b) {
replace($a, '\'||$b, '\\'||$b )
}
)
};
