This example reads a flat listing

The input to this example is the following XML file:

xmlExampleFlatListing.xml

<room type="Computer-Room">
  <location>CH-1211 Geneva 23
  <organisation>CERN
  <identification ref="513-R-050"/>
  <emergency phone="74444"/>
  <dimensions x="100m" y="80m" h="270cm"/>
  <air>18 degrees Celcius
  <air>65% relative humidity
  <air>20 millibars above outside pressure
  <equipment type="PC" quantity="8000">Quatro-Core 4GHz CPUs
  <equipment type="Network">Twenty 1-Gbps Connections
  <equipment type="Storage">Two Tape Storages of 20TBytes
</room>

The code in the example only calls ONCE the 'fwXml_childNodesContent()' function:

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

One checks if the return-code is effectively '0' because that means that the child-nodes are all element-nodes that contain at most one text-node as their child. The following is returned via the three output-parameters:

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 = room"]
WCCOAui1:["rtn_code = 0"]
WCCOAui1:["TagName = 'location' - Attribs = '' - Value-of-Child = 'CH-1211 Geneva 23'"]
WCCOAui1:["TagName = 'organisation' - Attribs = '' - Value-of-Child = 'CERN'"]
WCCOAui1:["TagName = 'identification' - Attribs = 'ref:513-R-050' - Value-of-Child = ''"]
WCCOAui1:["TagName = 'emergency' - Attribs = 'phone:74444' - Value-of-Child = ''"]
WCCOAui1:["TagName = 'dimensions' - Attribs = 'y:80m | x:100m | h:270cm' - Value-of-Child = ''"]
WCCOAui1:["TagName = 'air' - Attribs = '' - Value-of-Child = '18 degrees Celcius'"]
WCCOAui1:["TagName = 'air' - Attribs = '' - Value-of-Child = '65% relative humidity'"]
WCCOAui1:["TagName = 'air' - Attribs = '' - Value-of-Child = '20 millibars above outside pressure'"]
WCCOAui1:["TagName = 'equipment' - Attribs = 'quantity:8000 | type:PC' - Value-of-Child = 'Quatro-Core 4GHz CPUs'"]
WCCOAui1:["TagName = 'equipment' - Attribs = 'type:Network' - Value-of-Child = 'Twenty 1-Gbps Connections'"]
WCCOAui1:["TagName = 'equipment' - Attribs = 'type:Storage' - Value-of-Child = 'Two Tape Storages of 20TBytes'"]
WCCOAui1:["rtn_code = 0"]
