EvalTo functions with JDF

[cstevens]

Hello,



I'm trying to parse some data from a JDF ticket using the EvalToNodes() function, but don't seem to be having any luck.



Something like this:



var inputDIR = new Dir(job.getPath());

var jdfFileList = inputDIR.entryList("*.jdf", Dir.Files, Dir.Time);
var baseJDF = new Document(job.getPath() + "" + jdfFileList[0]);

var baseJDFdocElem = baseJDF.getDocumentElement();

var baseResourcePool = baseJDFdocElem.evalToNode("./jdf:ResourcePool", null);



I don't have issues using these functions on standard XML files, only with JDF. I've also tried with and without the "jdf:" prefix and no luck there. Do I need to do something with a prefix map to get this to work?



I can work around this using GetChildNodes() and parse the nodes for the base name that I need, but it would be a lot cleaner if I could use the EvalTo functions.

Yes, it is better to work with a prefix map. You can easily get that with:

var nsMap = baseJDF.createDefaultMap();



and you use nsMap as the second parameter in evalToNode.



Another thing, jdf: is used as the name of the default namespace for JDF files. For "normal" XML files the default namespace is referred to as dn:. As you are reading the JDF file as a normal XML file you should use dn:.

Thanks so much Freddy, I've been struggling with that one for months now.



Just so folks can see here's the working code:



var baseJDF = new Document(job.getPath() + slash + jdfFileList[0]);

var nsMap = baseJDF.createDefaultMap();

var baseJDFdocElem = baseJDF.getDocumentElement();

var baseRunList = baseJDFdocElem.evalToNodes("./dn:ResourcePool/dn:RunList", nsMap);

s.log(1, "Found " + baseRunList.length + " RunList elements in base JDF ticket.");
