[MarkLogic Dev General] xdmp:document-load - possible bug?

[Jacob Larsen]

Hi Justin

Isn't document-load() almost equal to document-get() + document-insert(), only with the handy feature of document repairing?
What I specify in the $location parameter is equal to document-get(), and what I have in the option $uri is equal to first parameter of document-insert() ?

Please correct me if I got things wrong.

Anyway, if a webserver answers 404, it means that there is no content. The HTML page saying "no page" is not the content.

Best

/Jacob

Jacob,
I think you're confusing xdmp:document-load with xdmp:document-get. The first parameter of document-load <http://developer.marklogic.com/pubs/4.1/apidocs/UpdateBuiltins.html#xdmp:document-load> is the document's unique identifier once it's successfully inserted into a database. This URI can be anything you want, as long as it's unique. document-load is the complement to fn:doc <http://developer.marklogic.com/pubs/4.1/apidocs/SequenceBuiltins.html#fn:doc>, which allows you to retrieve a document from a database using its unique ID. The first parameter of document-get <http://developer.marklogic.com/pubs/4.1/apidocs/Ext-7.html#xdmp:document-get>, on the other hand, is the location of the document to be retrieved outside of a MarkLogic database. You can use HTTP or filesystem locations. It returns either the document itself, or as Nuno has illustrated, a serialized HTTP response.

Hi All

I would appreciate your opinion on this, before I report it as a bug.

I load an xml files using something like:
xdmp:document.load("http://some-apache-server/some-xml-file")
  <options xmlns="xdmp:document-load">
      <repair>full</repair>
  </options>)

When http://some-apache-server/some-xml-file does not exist, apache reply "404 - Not Found" but also a simple HTML version of the error.
Mark Logic then creates a valid xml file from the HTML output, without checking the status code, and loads it.

I my view, this is clearly a bug. Every http GET request, should read the status code, and anything but 20* should result in some error from MarkLogic .

Any thoughts on this?

Best regards

Jacob
