How to read from NAV xml document using Microsoft XMLDOM automation


Usually i meet questions about "How to read from NAV xml documents without xmlports?"
It is because xml ports have some limitations and sometimes don't allow us to use it.
There is sample codeunit which reads xml nodes from file. It is just example and no more....:)


OBJECT Codeunit 50050 xml read
{
  OBJECT-PROPERTIES
  {
    Date=05.08.12;
    Time=15:13:32;
    Modified=Yes;

  }
  PROPERTIES
  {
    OnRun=BEGIN
            ffile.OPEN('C:\XmlFile.xml'); //this must be your file name
            ffile.CREATEINSTREAM(strInStream);


            IF ISCLEAR(xmldomDoc) THEN CREATE(xmldomDoc);


            xmldomDoc.load(strInStream);


            xmlNodeList1:= xmldomDoc.childNodes();



            FOR i:=1 TO xmlNodeList1.length()-1 DO BEGIN
             xmldomElem1:= xmlNodeList1.item(i);
                IF NOT ISCLEAR(xmldomElem1) THEN
                   xmldomAttrib:= xmldomElem1.getAttributeNode('ID');
                   IF NOT ISCLEAR(xmldomAttrib) THEN
                      txtid:=xmldomAttrib.value();
                   xmldomAttrib:= xmldomElem1.getAttributeNode('Type');
                   IF NOT ISCLEAR(xmldomAttrib) THEN
                      txttype:=xmldomAttrib.value();
                   xmldomAttrib:= xmldomElem1.getAttributeNode('Version');
                   IF NOT ISCLEAR(xmldomAttrib) THEN
                      txtVer:=xmldomAttrib.value();


                  //>>Find Node next level
                     xmldomElem2:=xmldomElem1.firstChild();
                     xmldomElem3:=xmldomElem2.firstChild();
                     xmldomAttrib:= xmldomElem3.getAttributeNode('Author');

                         txtAut:=xmldomAttrib.value();
                     xmldomAttrib:= xmldomElem3.getAttributeNode('TimeStamp');
                      IF NOT ISCLEAR(xmldomAttrib) THEN

                  //Next node


                  xmlNodeList2:= xmldomElem1.childNodes();

                   xmldomAttrib:= xmldomElem3.getAttributeNode('ID');
                   IF NOT ISCLEAR(xmldomAttrib) THEN

                   //go deeper

                   IF NOT ISCLEAR(xmldomAttrib) THEN

                  END;

Questions like "How to create xml files from NAV" are more easier, because you can use xmlport, dataport, write directly to file or use the same xmlDom automation.
