IXMLDOMNode for string?

Question

0.00/5 (No votes)

See more:

I have a string which contains the xml representation of an xml node which I intend to insert in a xml document loaded in memory. The xml string (of node)is something like this

XML

<ns1:Feature name=\"PageSize\">\
    <ns1:Option name=\"A4\" />\
 </ns1:Feature>

So , it has got namespace for the tag names as well.

Is there a way I can achieve this?

1)I tried to user XMLDomNode->put_text() , but it does not work as it replaces the "<" and ">" chars by their text representations (<etc.)

2) I was wondering if loading the string buffer in a separate in-memory xml document and then getting the node pointer from there will work on my original document. But again , not sure if the XMLDOMnodes are transferable within documents.

To import an XMLDOMNode from one xml to an other one, you have to use importNode from the IXMLDOMDocument3 interface.

you cannot add a node from an xml document inside an other document without importNode.

For example:

C++

MSXML2::IXMLDOMDocument3Ptr xml;
xml.CreateInstance(__uuidof(DOMDocument60));
MSXML2::IXMLDOMElementPtr elt = xml->createElement("root");
xml->appendChild(elt);

MSXML2::IXMLDOMDocument3Ptr subxml;
subxml.CreateInstance(__uuidof(DOMDocument60));
subxml->loadXML(fromString);

MSXML2::IXMLDOMNodePtr node = xml->importNode(subxml->GetdocumentElement(),VARIANT_TRUE);
elt->appendChild(node);

I did not check with subxml nodes that contains namespace.

DOMDocument60 is available when importing XML v6

C++

#import <msxml6.dll>
#include <msxml6.h>
#include <msxml.h>

I solved this myself using the 2nd approach:

1) Create an in-memory xml document based on

IXMLDOMDocument3

interface and load the xml string in there.

2) Select the node you require using the

selectNode()

method.

3) Now go back to your orinial xml document where you want the node placed and load it again as a IXMLDOMDocument3 interface.

4) Use the

C++

importNode()

method of IXMLDOMDocument3 from step 3 to clone the node obtained in step 2.

5) You can now use the cloned node to do an

appendChild()

to the original xml.
