NEWBIE:Cannot get to subnodes using getFirstChild and getNextSibl ing

[Williams Roger <RW...@OLDMUTUAL.com>]

Is there a way of getting pass these type of characters like Tabs,
Linefeeds,etc etc.

It would appear that the getNextSibling() function points to the same
element(most prolly a LineFeed+tab) everytime.

My xmldoc looks like:
<root>
	<properties>
		<propone>aaaa</propone>
		<proptwo>bbbb</proptwo>
	</properties>
	<surname>abcdef</surname>
</documentum_store_details>

code snippet:

bool Fn() { 
	...
	...
	...
	DOMParser Parser;
	Parser.parse(*memBufIS);

	DOM_Document DomDoc = Parser.getDocument();
	int nPropTags=-1,nProps=-1,i=0;
	DOM_NodeList NdLsPropTags =
DomDoc.getElementsByTagName("properties");  
	
	if ((nPropTags = NdLsPropTags.getLength())!=1) {
		if (nPropTags==0) {
			printf("No properties tag");
		}	
		else {
			printf("More than one properties tag");	
		}
		return false;
	}
	printf("\nPropTags\t%d\n",nPropTags);
	
	DOM_Node NdProp = NdLsPropTags.item(0); 
	DOMString dsNdNmProp = NdProp.getNodeName();
	char* pszNdNmProp = dsNdNmProp.transcode();
	printf("pszNdNmProp\t%s\n",pszNdNmProp);
	
	if(!NdProp.hasChildNodes()) 
		return true;
	
	DOM_Node Node;
	DOMString dsNdNmNode,dsNdVlNode;
	char *pszNdNmNode,*pszNdVlNode;
	int nNdTpNode=-1;i=0;
	bool flag1=true,flag2=true;
		
	while (flag1 && i<10) {
		if (flag2) {
			Node = NdProp.getFirstChild();
			flag2=false;
		}
		else {
			Node = NdProp.getNextSibling();
		}
		if (Node.isNull()) {
			printf("%d\n",i);
			flag1=false;
		}
		else {	
			nNdTpNode=-1;pszNdNmNode=NULL,pszNdVlNode=NULL;
			nNdTpNode = Node.getNodeType();
			dsNdNmNode = Node.getNodeName();
			if((pszNdNmNode==dsNdNmNode.transcode())==NULL) 
				pszNdNmNode="NULL";
			dsNdVlNode = Node.getNodeValue();
			if((pszNdVlNode==dsNdVlNode.transcode())==NULL) 
				pszNdVlNode="NULL";	
	
printf("%d\t%d\t%s\t%s\n",i,nNdTpNode,pszNdNmNode,pszNdVlNode);
		}
		i++;
	}
	printf("\ni\t%d\n",i);	
	return false;
}

The first child is a text node that contains an LF and space or tab
characters. The second child is propone.

No you don't. You get just the children of that node, which include text
nodes as well as element nodes.
