[C#] xml 파싱

xml Product_Key의 Name을 읽어서 ComboBox에 Items를 추가한다.

ComboBox의 List중에서 하나를 선택하면 Key의 값을 TextBox에 나타내 준다.

1. form1 디자인

ComboBox 이름 : cbname

TextBox 이름 : tbkey

2. xml 구조

<YourKey>
<Product_Key Name="1">
<Key>1</Key>
</Product_Key>
<Product_Key Name="2">
<Key>2</Key>
</Product_Key>
<Product_Key Name="3">
<Key>3</Key>
</Product_Key>
<Product_Key Name="4">
<Key>4</Key>
</Product_Key>
</YourKey>

3. form1 코드

xml.Load(url);
XmlElement keyList = xml.DocumentElement;

XmlNodeList xnList = xml.SelectNodes("/YourKey/Product_Key");

foreach (XmlNode node1 in xnList)
{
if (select)
{
string sKeyName = node1.Attributes["Name"].Value;
string sKey = node1["Key"].InnerText;
if (cbname.SelectedItem.ToString() == node1.Attributes["Name"].Value)
{
tbkey.Text = sKey;
}
}
else
{
string sKeyName = node1.Attributes["Name"].Value;
cbname.Items.Add(sKeyName);
}
}
}
catch (Exception)
{
throw;
}
}

}
