(C#) Iterate over Direct Children with a Specific TagDemonstrates how to iterate over direct children having a specific tag. The input XML, available at http://www.chilkatsoft.com/data/fruit.xml, is this: <root> <fruit color="red">apple</fruit> <fruit color="green">pear</fruit> <veg color="orange">carrot</veg> <meat animal="cow">beef</meat> <xyz> <fruit color="blue">blueberry</fruit> <veg color="green">broccoli</veg> </xyz> <fruit color="purple">grape</fruit> <cheese color="yellow">cheddar</cheese> </root>
Chilkat.Xml xml = new Chilkat.Xml(); Chilkat.Xml child = null; int numWithTag; int i; bool success; // The sample input XML is available at http://www.chilkatsoft.com/data/fruit.xml success = xml.LoadXmlFile("fruit.xml"); if (success != true) { Debug.WriteLine(xml.LastErrorText); return; } // Get the number of direct children having the tag "fruit" numWithTag = xml.NumChildrenHavingTag("fruit"); if (numWithTag > 0) { for (i = 0; i <= numWithTag - 1; i++) { child = xml.GetNthChildWithTag("fruit",i); Debug.WriteLine(Convert.ToString(i) + ": " + child.Tag + " : " + child.Content); } Debug.WriteLine("-----"); // Do the same as the above loop, but instead of creating // a new object instance for each child, call GetNthChildWithTag2 to // update the object's reference instead. for (i = 0; i <= numWithTag - 1; i++) { // Navigate to the Nth child. success = xml.GetNthChildWithTag2("fruit",i); Debug.WriteLine(Convert.ToString(i) + ": " + xml.Tag + " : " + xml.Content); // Navigate back up to the parent: success = xml.GetParent2(); } Debug.WriteLine("-----"); } |
