Using XPATH in RTF: count, starts-with, name functions

https://docs.oracle.com/cd/E80149_01/bip/BIPRD/GUID-4D9FC5FC-5A72-4CE6-919C-A3E0D6E4900C.htm#BIPRD2597

 XPath contains a number of functions on node sets, numbers, and strings; here are a few of them:

  count(elem) counts the number of selected elements

  Example: //section[count(student)=1] selects section with exactly two students children

  name() returns the name of the element

  Example: //*[name()='student'] is the same as //student

  starts-with(arg1, arg2) tests if arg1 starts with arg2

  Example: //*[starts-with(name(), 'stu']

  contains(arg1, arg2) tests if arg1 contains arg2

  Example: //*[contains(name(), 'tud']

Type		Output
Count elements (Students) in XML		<?count(STUDENT)?>
Name of the Element if exists		<?//*[name()=’ROLL_NO’]?>
Starts-with		<?//*[starts-with(name(), 'ROLL_NO')]?>

OUTPUT IS RETURNED AS BELOW:

Type		Output
Count elements (Students) in XML		3
Name of the Element if exists		1201
Starts-with		1201

check earlier post for xml, save above in rtf file, and output will be shown as shown above
