I have the following method that is supposed to return a string that holds the calories for a given food item in an xml menu.
public string calorieCount(int choice)
{
string calCount = "250";
XmlDocument doc = new XmlDocument();
doc.Load(path);
XmlElement root = doc.DocumentElement;
XmlNode node = doc.SelectSingleNode("/menu/item[@name='Burger']/calories");
string checker = node.Value;
MessageBox.Show(checker);//returning nothing
return checker;
}
And my XML file looks like this:
<?xml version="1.0" encoding="utf-8" ?>
<menu>
<!-- Burger -->
<item name="Burger">
<name>Burger</name>
<price>$5.99</price>
<calories>500</calories>
<description>A burger made with 100% angus beef and grilled to your liking. Served with fries</description>
<count>25</count>
</item>
Why is it returning an empty string? Is my call to SelectSingleNode
incorrect?
Thank you in advance.
Use InnerText
instead of Value
Replace
string checker = node.Value;
With
string checker = node.InnerText;
