with my code I am trying to grab the path data from a xml (used to be svg) file and while I am able to successfully print out the data by the $attributes array, using echo it still pulls up the "call to a member function attributes() on a non-object in (line 136 and 156) I simply don t see what is wrong with the code, although worst case scenario I can always use a hack around that inserts the selected data into a db within the while loop and upon iteration forward to the desired page... I am wondering what exactly is wrong with my code. it echos out the correct information with the echo commands. it just still gives the call to a member function on a non object error

while($number_of_array_path >=1)
{
//declares attributes based on path number for sodipodi attributes line136
$attributes = $xml_file_open->g->path[$path_incremental_counter]-
>attributes( sodipodi , true); 

//sets each attribute within an array and uses the path incremental counter for 
//that pourpose.
$type_array[$path_incremental_counter] = $attributes[ type ];
$cx_array[$path_incremental_counter] = $attributes[ cx ];
$cy_array[$path_incremental_counter] = $attributes[ cy ];

$ry_array[$path_incremental_counter] = $attributes[ ry ];
