Read next value in XML file

Question

I have a XML file like that:

    <key>businessAddress</key>
    <string>Moka</string>
    <key>businessName</key>
    <string>Moka address</string>
    <key>Id</key>
    <string>39</string>
    <key>Cat</key>
    <string>216</string>
    <key>deals</key>

I want to read the next <string> value if the key is Id

So what I did is this:

XmlTextReader reader = new XmlTextReader(file);

while (reader.Read())
{
    if (reader.Value.Equals("Id"))
    {
        reader.MoveToNextAttribute
    }  
}

but I didn't succeed.

Thanks for help

You could use a boolean flag to indicate whether you should read the value of the next element:

bool shouldReadId = false;
while (reader.Read())
{
    if (reader.NodeType == XmlNodeType.Text && shouldReadId)
    {
        Console.WriteLine(reader.Value); // will print 39
        shouldReadId = false;
    }

    if (reader.Value.Equals("Id"))
    {
        // indicate that we should read the value of the next element
        // in the next iteration
        shouldReadId = true;
    }
}
