given your advice xerces message is all gone, now i am facing another
message, sorry if bothering, i am to try to compile this tutorial:
http://vichargrave.com/xml-parsing-with-dom-using-c/ wich has main.cpp,
XmlDomDocument.cpp and XmlDomDocument.h.
*main.cpp*
#include <stdio.h> #include <stdlib.h> #include <string> #include

int main(int argc, char** argv) { string value; XmlDomDocument* doc =
new XmlDomDocument("./bookstore.xml"); if (doc) { for (int i = 0; i < doc
->getChildCount("bookstore", 0, "book"); i++) { printf("Book %d\n", i+1);
value = doc->getAttributeValue("book", i, "category"); printf("book
category - %s\n", value.c_str()); value = doc->getChildValue("book", i,
"title"); printf("book title - %s\n", value.c_str()); value = doc->
getChildValue("book", i, "author"); printf("book author - %s\n", value.
c_str()); value = doc->getChildValue("book", i, "year"); printf("book
year - %s\n", value.c_str()); value = doc->getChildValue("book", i, "price"
); printf("book price - %s\n", value.c_str()); } delete doc; }
