This example reads hierarchical data

The input to this example is the following XML file:

xmlExampleHierarchical.xml

<Earch>
 <Europe>
  <England lan="E">
  </England>
  <Switzerland lan="F/I/D">
   <Geneva lan="F">
    <Geneva/>
    <Meyrin/>
    <Versoix/>
   </Geneva>
   <Bern lan="D">
    <Bern/>
   </Bern>
   <Valais lan="F/D">
    <Sion lan="F"/>
    <Martigny lan="F"/>
   </Valais>
  </Switzerland>
 </Europe>
 <America>
  <Usa lan="E">
   <New-York/>
   <Florida>
   </Florida>
  </Usa>
  <Brazil lan="P">
  </Brazil>
  <Argentina lan="E"/>
 </America>
</Earch>

The code in the example calls the 'fwXml_childNodesContent()' function more than once:

rtn_code = fwXml_childNodesContent ( xml_doc_ident , top_elem_ident , node_names , attributes , nodevalues , exInfo );

The return-code in this example is '2' even though the child-nodes are only element-nodes, but they in turn contain below them element-nodes, thus the returned value is [1<

The program then prints out the returned information in the three dynamic variables in the following form:

WCCOAui1:["document = 0"]
WCCOAui1:["1-child = 0"]
WCCOAui1:["topelem = [0] 'Earch'"]
WCCOAui1:["rtn_code = 2"]
WCCOAui1:["TagName = [1]    'Europe'"]
WCCOAui1:["rtn_code = 2"]
WCCOAui1:["TagName = [2]       'England'   Attribs 'lan:E'"]
WCCOAui1:["TagName = [2]       'Switzerland'   Attribs 'lan:F/I/D'"]
WCCOAui1:["rtn_code = 2"]
WCCOAui1:["TagName = [3]          'Geneva'   Attribs 'lan:F'"]
WCCOAui1:["rtn_code = 0"]
WCCOAui1:["TagName = [4]             'Geneva'"]
WCCOAui1:["TagName = [4]             'Meyrin'"]
WCCOAui1:["TagName = [4]             'Versoix'"]
WCCOAui1:["TagName = [3]          'Bern'   Attribs 'lan:D'"]
WCCOAui1:["rtn_code = 0"]
WCCOAui1:["TagName = [4]             'Bern'"]
WCCOAui1:["TagName = [3]          'Valais'   Attribs 'lan:F/D'"]
WCCOAui1:["rtn_code = 0"]
WCCOAui1:["TagName = [4]             'Sion'   Attribs 'lan:F'"]
WCCOAui1:["TagName = [4]             'Martigny'   Attribs 'lan:F'"]
WCCOAui1:["TagName = [1]    'America'"]
WCCOAui1:["rtn_code = 2"]
WCCOAui1:["TagName = [2]       'Usa'   Attribs 'lan:E'"]
WCCOAui1:["rtn_code = 0"]
WCCOAui1:["TagName = [3]          'New-York'"]
WCCOAui1:["TagName = [3]          'Florida'"]
