Welcome to the p2p. These patterns are used by XSLT to perform transformations. For example if the array contains {1,2,3,2,1,4} then {1,2} duplicate elements and output should be 2. The root element must encapsulate all other elements--meaning, these other elements must show up after the opening root tag and before the closing root tag. For Example, In the above tree, the count will be 1 as there is only one such node which is ‘2’ which has more number of children than its parent. There are many options available out there. If you need to total all the sub nodes as well, then it is a simple recursion on each node. Here lets see simple Java code to create Captcha and to test with web application using JSP. For example, the following will count the total number of para elements in the XML document, so the result is a number:. A window will pop up. The result I get is that there are 5 nodes and the node names are: #Text, slide, #Text, slide, #Text Can anyone explain to me how--based on the xml file below, there are 5.
