About AttrImp()
Dear Sir,
About 2 weeks before, I asked a question to the Xerces-c mailing list. But
the next day, by mistake I deleted all the mails from Xerces-c mailing list.
Only by today I read your answer from the Xerces-c mailing list Homepage.
Thank you very much for the answer.
Here, I am still not very sure about 2 points:
1. Is it OK to say that there's only 1 child for each DOM_Document Node, and
that's just the result of doc.getDocumentElement. ( I tested by using
doc.getFirstChild and doc.getLastChild )
2. I wonder why there should be "5 child nodes of n1"? From the result you
gave, n1 stands for "document" element. I tested by myself also and got same
results: 5 child nodes for "document". To find the answer, I rewrite the xml
data as the following:
<document>
<certification/>
</document>
This time I got the result of 3 which I can't explain at all.
The main source is written in the following and I have set
parser.setIncludeIgnorableWhitespace(false);
DOM_Document doc = parser.getDocument();
DOM_Element element = doc.getDocumentElement();
cout << "Count of child nodes :" << element.getChildNodes().getLength()
<< endl;
Thanks a lot,

| Not in all cases. There will always be only 1 _element_ child for

| The white space becomes text nodes. The children of the "document" element
| are a text node, an element node ("certification"), and a text node. The
| first text node contains the white space before the "certification"
element
| and the second text node contains the white space following the
| "certification" element. (XML requires XML processors to keep _all_ of the
| content.) If you change your XML data to:
|
| <document><certification/></document>
|
| Then the result will be a single child node for the "document" element.
