IF Condition:

<?if:P_PM_YN=’N’?> Yes <?end if?>


IF ELSE Condition:

Method 1:

<?xdofx:if element_condition then result1 else result2 end if?>

Example:

<?xdofx:if INVOICE_AMOUNT > 5000 then ’Higher’
else
if INVOICE_AMOUNT <3000 then ’Lower’
else
’Equal’
end if?>

Method 2:
Syntax:

<?xdoxslt:ifelse(condition,true,false)?>

Example: 

<?xdoxslt:ifelse(20=21,’yes 20 and 21 are equal’,’No 20 and 21 are not equal’)?>

Ans: No 20 and 21 are not equal

Using OR Condition in XML RTF Template:

Syntax:

<?if:XMLfield=value1 or XMLfield=value2?> display value <?end if?>

Example:

<?if:sum(AVALUE)=0 or sum(BVALUE)=0?>0<?end if?>

You can use whichever is applicable to your requirement.

 -------------------------------------------------------------------------------------------
 VALUE-OF
This element is used to retrieve a value from a specified Element or Attribute. For example, if you used this element specifying ‘/DATA/DEPARTMENT/NAME’ then you can retrieve a value that is presented in the NAME element in the XML document.

With BI Publisher tags, you can just type the following to do the same.

<?/DATA/DEPARTMENT/NAME?>

 --------------------------------------------------------------------------------------------

FOR-EACH

With BI Publisher tags, you can type the following to do the same.

<?for-each:/DATA/DEPARTMENT?>
  <?NAME?>
<?end for-each?>

------------------------------------------------------------------------------------------------------------------------------------------------------------

XSL:SORT
Inside the previous ‘for-each’ loop you might want to sort the data by alphabetically or based on the ID, etc. You can use this ‘sort’ element to do the sorting.

With BI Publisher you can do the following to achieve the same. 

  <?sort:NAME;’ascending’;data-type=’text’?>

---------------------------------------------------------------------------------------------------------------------------------------------------------------- 

IF
You can use this element to have a condition in the XSL transformation logic. This is also pretty much the same as other programming language’s ‘if’ condition. For example, if you want to display manager name only when Department name is ‘Consulting’ you can specify something like the below.

You can do the same with BI Publisher tags as follows.

<?for-each:/DATA/DEPARTMENT?>
  <?if:NAME=’Consulting’?>
    <?NAME?>
  <?end if?>
<?end for-each?>

---------------------------------------------------------------------------------------------
 CHOOSE
As an alternative or for better reasons you can also use CHOOSE/WHEN elements to do the condition. One thing to note is that XSL doesn’t support IF/ELESE condition as native, so if you have multiple conditions to use together in a form of IF/ELSE then CHOOSE/WHEN/OTHERWISE elements would serve you better.

With BI Publisher you can do the below to have the same condition. 

<?for-each:/DATA/DEPARTMENT?>
  <?choose:?>
  <?when:NAME=’Consulting’>
    <?MANAGER_NAME?>
    <?DEPARTMENT_NAME?>
  <?end when?>
  <?otherwise:?>
    <?DEPARTMENT_NAME?>
  <?end otherwise?>
  <?end choose?>
<?end for-each?>
