Hi,

I am using '9.2.0.538062 (R2017a)' version, and I want to parse xml to csv,and I want to access the attributes for example:

bk103: Author, title, genre, price, publish etc.

I use the below code,

close all
clear all
clc
c=xml2struct('D:\Mekala_Backupdata\PythonCodes\testxml2.xml');

my xml file:

<?xml version="1.0"?>
