[erlang-questions] Re: xmerl and $'

[Mark Fine]

Huh? In my actual application, I've got lots of values being returned
in a single document -- I want to preserve these values, not
concatenate them altogether.

problem3() ->
    Xml = "<?xml version=\"1.0\"
encoding=\"UTF-8\"?>\n<Keys><Key>There's a
problem</Key><Key>There&s another problem</Key></Keys>",
    {Doc, _} = xmerl_scan:string(Xml),
    [Value || #xmlText{value = Value} <-
xmerl_xpath:string("//Key/text()", Doc)].

returns ["There","'s a problem","There","&s another problem"] instead
of ["There's a problem","There&s another problem"]. And I definitely
don't want ["There's a problemThere&s another problem"].

So far, preprocessing the XML seems necessary -- I go through and map
' to __APOS__ and & to __AMP__ before xmerl_scan:string(),
and then map back -- this is the only way so far I've figured out how
to make this work.
