[OPEN-ILS-DEV] Retrieving and parsing MARC records from the Web interface

[Alexander O'Neill]

Hello all, new evergreen person here.

I have a question about retrieving MARC records.  I am writing a  
modification to the web interface, specifically on the rdetail page,  
to print a specific entry from a MARC record  just under the main  
results table without the user having to click on the MARC Record tab  
below to see it.

What I have right now is that I can, when the page loads, call the  
FETCH_MARC_HTML (open-ils.search:open-ils.search.biblio.record.html)  
request method, and in the callback function print the contents of the  
response object.

Now, before I go and parse through the raw HTML, is there a better way  
to get the MARC record, as, say, a JSON object?  I tried a few  
different function calls and none seemed to return any data.  I am  
using the Debian 1.2.2.3 VMWare image with the default setup.

Here's the code snippet I have right now that does the job before I do  
any HTML parsing:

  var req = new Request( "open-ils.search:open- 
ils.search.biblio.record.html", record.doc_id() );
  req.callback(rdetailCategoriesCallback);
  req.send();
}

function rdetailCategoriesCallback(r, id) {

  var marcrecord;
  marcrecord = r.getResultObject();
  $('rdetail_categories').appendChild(text(marcrecord));


}


Thanks for your help.

Regards,
