I am trying to do an XML Parsing by getting a token and implementing them to my databases which I`ve created through them at SQLite database. This is a coffee shop order app I should parse the data I got through the token and implement the data (table_id, table_status, product_id, product_title, product_price) into my databases so they will Now I have two tables "products" and "tables" even though I got the token from the CTower which is "429925" and have an output like this
"3-OK 1410 1420 1430 1440 1450 1460 1470 1480 1490 14 2.00 9 3.00 13 1.50 5 1.50 2 3.00 1 2.50 7 4.00 6 1.50 12 2.50 15 4.00 3 2.00 4 2.50 16 4.00 10 3.00 8 3.50 11 3.00"
I should imply this into the tables ("products" and "tables") and have an outcome like:
<?xml version="1.0" encoding="utf-8"?>
<response>
<status>3-OK</status>
<msg>
<tables>
<table>
<id>501</id>
<status>1</status>
</table>
<table>
<id>502</id>
<status>0</status>
</table>
……….
</tables>
<products>
<product>
<id>14</id>
<title>Capuccino</title>
<price>2.00</price>
</product>
<product>
<id>9</id>
<title>Chamomile</title>
<price>3.00</price>
</product>
……….
</products>
</msg>
</response>
I tried the code below and many others but can not make the parsing apparently, can you detect what seems wrong here? Please ignore the 0-fail,0-ok,1-fail,1-ok,2-fail,3-ok,3-fail parts they are for another activity. I would appreciate any help, thank you!
