Ah, the quotes mix up. I didn't consider that. The criteria I was using to access some of the nodes was in the form:

my $query = "//property[color = 'Blue']/OtherProperty/text()";

This threw me off. I switched to using the single (literal) quotes and this has helped quite a bit. However I am still curious if there are other "/text()" style path calls. (Just in case there are better ways of doing things.)

Thanks for you help.

[Cosmic37]: rather than the value of $mydt which is a date time strong such as 2016-01-01 12:30:56
[Corion]: Cosmic37: No, but maybe $mydt doesn't contain what you think it does, or it contains characters that are special in a regular expression? Try if( $line =~ /\Q$mydt\E/) { ... for a literal match
[Cosmic37]: I mean string grrr
[Corion]: Maybe add an else branch in which you print what the values of $line and $mydt are?
[Cosmic37]: ah thank you I will try
[Cosmic37]: you are right $mydt did not contain what I expected... :-D I will now think :-D
