(Android™) Remove an XML SubtreeDemonstrates how to remove an XML subtree from an XML document.
// Important: Don't forget to include the call to System.loadLibrary // as shown at the bottom of this code sample. package com.test; import android.app.Activity; import com.chilkatsoft.*; import android.widget.TextView; import android.os.Bundle; public class SimpleActivity extends Activity { private static final String TAG = "Chilkat"; // Called when the activity is first created. @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); CkXml xml = new CkXml(); boolean success = xml.LoadXmlFile("qa_data/xml/osszes.xml"); // The XML file we're loading contains this: // <?xml version="1.0" encoding="iso-8859-2" ?> // <EXAMPLE> // <OSSZES> // <ROW TYPE="INS">477953 // <NUMBER>05107003972</NUMBER> // </ROW> // <ROW TYPE="INS">477954 // <NUMBER>05107001342</NUMBER> // </ROW> // <ROW TYPE="INS">477955 // <NUMBER>05107001342</NUMBER> // </ROW> // <ROW TYPE="INS">477956 // <NUMBER>05107000017</NUMBER> // </ROW>** // <ROW TYPE="INS">477957 // <NUMBER>05107002182</NUMBER> // </ROW> // </OSSZES> // </EXAMPLE> // // We wish to remove this subtree: // <ROW TYPE="INS">477956 // <NUMBER>05107000017</NUMBER> // </ROW> // Get another reference to the XML document. CkXml xml2 = xml.GetSelf(); // Navigate to the node that is the root of the subtree to be deleted. // In this case, we wish to find the node having tag "ROW" with content "477956" String notUsed = xml2.chilkatPath("OSSZES|/C/ROW,*477956*|$"); // Examine the xml2, it should be just the subtree. Log.i(TAG, xml2.getXml()); // Now detach xml2 from the it's XML document. // xml2 will now be it's own XML document. xml2.RemoveFromTree(); // Examine our original XML document. The subtree is removed: Log.i(TAG, xml.getXml()); } static { System.loadLibrary("chilkat"); // Note: If the incorrect library name is passed to System.loadLibrary, // then you will see the following error message at application startup: //"The application <your-application-name> has stopped unexpectedly. Please try again." } } |
