Question

<element1 type="type1" name="value1">
  <start play="no"/>
  <element2 aaa="AAA"/>
  <element2 bbb="BBB"/>
  <element3 ccc="CCC">
     <element4/><!-- play="no"/>-->
  </element3>
</element1>

And I use following code to parse it:

int parse( const char *xml) {

    printf("Entered\n");
    xmlDoc  *doc = NULL;
    doc = xmlReadFile(xml, NULL, 0);

    if (doc == NULL)
        printf("Could not parse file\n");
    else {
        printf("Success\n");
        xmlFreeDoc(doc);
    }

    xmlCleanupParser();
    return 0;
}

But I get following error:

Entered
I/O warning : failed to load external entity "<element1 type="type1" name="value1">
  <start play="no"/>
  <element2 aaa="AAA"/>
  <element2 bbb="BBB"/>
  <element3 ccc="CCC">
     <element4/><!-- play="no"/>-->
  </element3>
</element1>

"
Could not parse file

Answer 1

I believe the first argument to

xmlReadFile(xml, NULL, 0);

is the name of the file, not the XML string itself. The error message indicates that you passed the actual XML to the method. I believe there is an xmlReadMemory() method that will suit your needs.
