Re: [Exist-open] What goes wrong here (fn:matches and regular expression))

[Rob v. S. <va...@nl...>]

Kevin,

Thanks for your answer. I'm familiar with the use of  |= and &=.  The 
point is that I try to find records where I have an exact (case 
insensitive) match of  a text node with the word I'm looking for (like 
<keyword>radar</keyword>). The strange thing is that I my query (using 
$record/* = "radar") does not return anything but when I use $record/* 
|= "radar" it does. But then I also find the records with text nodes 
containing other text (like <keyword> radar optical</keyword>).

Regards,
Rob
