Title: XML - Lesson 8-Adding the functionality that allows us to delete a book
Duration: 18 minutes
Summary: This video continues the application we started. We will add the functionality that allows us to delete a book. When deleting a book, we use an xpath expression to select the appropriate node. If that node is found, we remove it from the tree. We save the document and load it again. We also support the ability to browse the books in the XML file. To do so, we add the code for First, Previous, Next, and Last buttons. Any time the user clicks on those button, the content of the text boxes and the index label change accordingly.
Methodology of the development of example: Good coding standard and simplified design to illustrate the key points.
