        </imagenes>
    </anuncio>
</saltest3>

My problem is that the if statement is not returning true , Any idea where I am going wrong

Thanks in advance

Answer 1

It is because you have too many mis-matched tags in your XML starting right at the top with <saltest31>...</saltest3> . This will cause a 0 to be returned.

In addition xml_parse_into_struct() returns a 1 or a 0 which really shouldn't be mistaken for true and false. From the docs ,

xml_parse_into_struct() returns 0 for failure and 1 for success. This is not the same as FALSE and TRUE , be careful with operators such as ===.

Given that, you should perform the test explicitly:

$p = xml_parser_create();
if (xml_parse_into_struct($p,$contenido,$vals, $index) == 1)
{
    print_r($vals);
}
