Ah, I didn't know about Class::XPath. Looks very nice, and almost exactly what the doctor ordered.

As far as I can see, Data::Diver doesn't allow the more general kind of querying which the OP requested.

And whilst LDAP has a special place in my heart, as far as I know, it has the same schema issues which SQL does. LDAP object classes need to be defined in terms of mandatory and optional attributes, the attributes need to have an appropriate syntax. Basically LDAP object class == SQL table, LDAP attribute == SQL column. The main differences IMHO are that LDAP gives you a heirarchically-defined name for each entry and SQL gives you a richer query language.

I would agree that DBs aren't the answer to everything, but they are an answer to "how do I do fairly arbitrary queries to my structuted data".

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
