can I use a user variable for xpath_expr

[Steffen Sens]

Hallo,

it is not possible to put a variable for xpath_expr instead a string like '//a/b[1]' in function

extractValue(xml_frag, xpath_expr)

For xml_frag it is possible to use a variable.

I would love to keep a whole xpath_expr whithin a variable and run the function like

set @xml := load_file('/tmp/test.xml');
set @xpath = '//a/b[1]';

extractValue(@xml, @xpath);

....or

extractValue(@xml, $@xpath);

...but both does not work...or?


best regards
Steffen Sens
