XML with empty attributes

Hunki · 2011-10-31

I wrote some code to create an xml-file with XML-Dom in Navision 2009 SP1.

Till here, this is nothing special. The problem is, that every time I add an attribute to a node it will create a empty attribute on the next element.

<?xml version="1.0" encoding="ISO-8859-1"?>
<DeclareSalary xmlns="http://www.swissdec.ch/schema/sd/20090803/SalaryDeclarationServiceTypes">
<RequestContext xmlns="http://www.swissdec.ch/schema/sd/20090803/SalaryDeclarationContainer">
<UserAgent xmlns=""/>
<CompanyName xmlns=""/>
</RequestContext>
</DeclareSalary>

What can I do that these empty attributes will not occur? Does anybody has a idea?

No, i cannot create it with XML-Ports.... the code is to complex to simly use an xml port.

Thanks
Patrick

Can you show us the code where you are exporting
<UserAgent xmlns=""/>
<CompanyName xmlns=""/>

these attributes?

Sure... here is the code:

IF cNamespaceIn <> '' THEN BEGIN
rNameSpaceLoc.GET(cNamespaceIn);
autElementVar := autXMLDoc.createNode(1,tNameIn,rNameSpaceLoc.URI);
END ELSE
autElementVar := autXMLDoc.createNode(1,tNameIn,'');

IF tDataIn <> '' THEN
autElementVar.text := tDataIn;
autParentIn.appendChild(autElementVar);

In this case the value in tDataIn is always empty... so only the functions createNode and appendChild will be called.

If you dont want to create with empty value try with

IF tDataIn <> '' THEN BEGIN
  autElementVar.text := tDataIn; 
  autParentIn.appendChild(autElementVar);
END;

That's not possible, because I need this element... but not the empty attribute.

I just found something very interessting:

The original code to set the attribut looks like this:

IF rLineIn.Namespace <> '' THEN BEGIN
rNameSpaceLoc.GET(rLineIn.Namespace);
tAttrNameLoc := 'xmlns';
autParentIn.setAttribute(tAttrNameLoc,rNameSpaceLoc.URI);
CLEAR(rNameSpaceLoc);
END;

this creates the following XML-File:

<DeclareSalary xmlns="http://www.swissdec.ch/schema/sd/20090803/SalaryDeclarationServiceTypes">
<RequestContext xmlns="http://www.swissdec.ch/schema/sd/20090803/SalaryDeclarationContainer">
<UserAgent xmlns="">
<Producer>Microsoft Corporation</Producer>
<Name>Microsoft Dynamics NAV</Name>

But if I change the code like this:

IF rLineIn.Namespace <> '' THEN BEGIN
rNameSpaceLoc.GET(rLineIn.Namespace);
tAttrNameLoc := 'xmlnsx';
autParentIn.setAttribute(tAttrNameLoc,rNameSpaceLoc.URI);
CLEAR(rNameSpaceLoc);
END;

the XML-File looks like this:

<DeclareSalary xmlnsx="http://www.swissdec.ch/schema/sd/20090803/SalaryDeclarationServiceTypes">
<RequestContext xmlnsx="http://www.swissdec.ch/schema/sd/20090803/SalaryDeclarationContainer">
<UserAgent>
<Producer>Microsoft Corporation</Producer>
<Name>Microsoft Dynamics NAV</Name>

This will be how it looks like, with exception of the attribut
