Doesn't work on all valid MARCspec

[coandco]

Hi!
I'm trying to use php-marc-spec to parse the MARCspec 5..$a{^1=3} ("give me the 'a' subfield of all 5xx fields whose first indicator is equal to 3"), but php-marc-spec improperly parses it to lump the subspec in with the subfield:

Array
(
    [0] => 5..$a{^1=3}
    [field] => 5..
    [1] => 5..
    [tag] => 5..
    [2] => 5..
    [subfields] => $a{^1=3}
    [4] => $a{^1=3}
)

Am I missing something? It seems like it should be valid MARCspec.

Hi there! I like to look into it. I hope to find time very soon. Sorry for letting you wait.

We have the same problem here. A workaround is to repeat the field and add a backslash to the indicator value.

So, 5..$a{^1=3} would become 5..$a{5..^1=\3}.
