[XML] DOM Parser code: it is ok but not print the node value

[takeokikuta]

I wrote the follow code.
It's ok but not print the node value.
I don't understand.
What is my error? Thanks

Code: Select all

#include <stdlib.h>
#include <iostream>
#include <Poco/XML/XMLString.h>
#include <Poco/DOM/Document.h>
#include <Poco/DOM/Node.h>
#include <Poco/DOM/NodeList.h>
#include <Poco/DOM/DOMParser.h>

using namespace std;

int main(int argc, char** argv) {

    Poco::XML::DOMParser *domParser = new Poco::XML::DOMParser();
    Poco::XML::Document *doc = NULL;
    Poco::XML::Node *node = NULL;
    Poco::XML::NodeList *nodeList = NULL;
   
    Poco::XML::XMLString *iFile = new Poco::XML::XMLString("book.xml");
    Poco::XML::XMLString *tagTitle = new Poco::XML::XMLString("title");
   
    doc = domParser->parse(*iFile);
    nodeList = doc->getElementsByTagName(*tagTitle);
    node = nodeList->item(0);
   
    cout << node->nodeName() << ": " << node->nodeValue() << endl;
   
    return (EXIT_SUCCESS);
}

Xml file is:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE books SYSTEM "book.dtd">
<books>
    <book>
        <title><![CDATA[L'eretico]]></title>
    </book>
</books>

DTD file is:

Code: Select all

<?xml version='1.0' encoding='UTF-8'?>
<!ELEMENT books (book)*>
<!ELEMENT book (title)*>
<!ELEMENT title (#PCDATA)>

nodeValue() does not give you the content of an Element. You can use innerText() (which is not part of the standard DOM, but a POCO extension) instead of nodeValue().

PS: You might also want to think about the excessive, but unnecessary use of new in your code...
