Version 5 XML load using XML v6.0 DOMDocument for XML file with schema

borealis · 2017-11-10

Client is running version 5.0.33335

Apologies if this is an answered question, I'm not having a lot of luck trying to search for answers on this one.

In the past I've found and used code to read in XML documents for ancient NAV using the 'Microsoft XML, v6.0'.DOMDocument60 control without issue. I'm not actually particularly proficient with this as most of our clients use later versions of NAV that allow me to use XML ports, but for this particular client upgrading is unfortunately not likely to happen in the forseeable future.

So my past code would simply use the XMLDoc.load command and then parse through the child nodes in a fairly straightforward way. Now, however the customer wants to receive XML documents that have a schema. Specifically <ORDER version="2.1" type="standard" xmlns="http://www.opentrans.org/XMLSchema/2.1" xmlns:bmecat="http://www.bmecat.org/bmecat/2005">. When I use the load command it returns false every time. As an experiment, I stripped out the schema specific stuff from a sample of it and the load proceeded just fine and my child nodes were where I expected them.

I could, in theory, write a routine to strip out the schema stuff before proceeding on to my processing however if possible I'd like to avoid that. Is there a way that I'm missing?

Past code was essentially this:

IF ISCLEAR(XmlDoc) THEN
  CREATE(XmlDoc);

XmlDoc.async(FALSE);
okay := XmlDoc.load(Param.FileName);
IF NOT okay THEN
  ERROR('That did not work');  // log an error

CLEAR(EDIOrderHeader);
InitNewOrder(EDIOrderHeader);
XmlNodeList := XmlDoc.childNodes;
FOR i := 0 TO XmlNodeList.length - 1 DO BEGIN
  XmlNode := XmlNodeList.item(i);
  ReadChildNodes(XmlNode,EDIOrderHeader);
END;

If the problem is loading the XML file, looks like the file maybe is not a correct XML.

Could you put an example of this XML file ?

Regards

borealis · 2017-11-10

I believe the issue is the fact it's running with two schemas. The Opentrans one, and the bmecat one. I've seen different XML controls that provide methods for loading those schemas, often in C++ but I have no idea how I might do that with this control in NAV with C/AL.

ftornero,

For some reason I cannot get your codeunit to work. It fails on the error when unable to load the file. The only change I made was to change the file/directory and the field name for the "picture" field in company information used as a temp table (which it never gets to since the error is before that).

ftornero · 2017-11-11

I don't know what to say, it's work for me, running the codeunit I get this message

The problem could be thatyou don't have enough permissions in the directory.

Regards

borealis · 2017-11-12

After a bit of research on how to determine error codes, the problem turned out to be an illegal character. The sending company is german and had an ascii 129 (the u with two dots). I sanitized the company name in the xml file I pasted here which is why it wasn't a problem for you.

Is there a way to specify the allowable character set with the DOMDocument before the load? I'm looking at the MSDN set of methods for the objects but nothing is jumping out at me.

ftornero · 2017-11-12

In this case is a codification problem.

I changed the file from ANSI to UTF-8, inserted the u with two dots, and I loaded the file without a problem again.

borealis · 2017-11-13

Is there any way to specify the encoding of the file though prior to passing it through the load method? The XML envelope unfortunately doesn't specify the encoding, so it makes it somewhat problematic. All the xml from this particular client will likely be in the same format, so I shouldn't have to worry about inconsistency but I don't know how to tell the DOMDocument which encoding to use.

ftornero · 2017-11-14

What is the format of the file ?

If always is the same you can change to UTF-8 before loading.

Regards.

Howdy, Stranger!
