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 ) } ) }; --Marc On Fri, Aug 15, 2014 at 11:55 AM, Rob Stapper <r.stapper@lijbrandt.nl> wrote:
Hi,
How can I construct the relative path between two elements in an xml-file.
Most probably overlooking the obvious I ended up with the solution below, which, unfortunately, triggers an runtime-error.
My not-working solution:
let $xml :=
<xml>
<A>
<B/>
</A>
</xml>
let $b := $xml//B
let $a := $xml//A
return replace( string( path( $b))
, string( path( $a))
, ''
)
Two questions:
- How to retrieve the relative path between two element within a xml-file?
- Why does the solution above trigger an error? Can it be a bug? ( oops, three questions)
Thnx in advance for the reply,
Rob Stapper
