Regarding Stream serve version 5.6.2 [ST]

There was an error rendering this rich post.

In Storyteller, we have lines in Block_Lines/Block_Line
Requirement is to suppress duplicate item if exits

I have added a logic to identify the duplicate item and push a value in variables and in line repeater have added condition in XPath

It does not work

Any suggestion how to fix it.

Hi.

if you want to skip duplicate lines, why do you add 'linenumber' as part of the 'array-search-string'?

wouldn't then all lines be unique… ;-)

and maybe also use the function: FindStringExactInArray()

For list of lines with unique ItemNumber, did you try pure XPath? Something like

Block_Lines/Block_Line[not(ItemNumber = preceding-sibling::Block_Line/ItemNumber)]

Translated to human, the condition reads: select all Block_Line elements that have ItemNumber that does not match any of the previous Block _Line element’s ItemNumber.

Elegant as it is, keep in mind that there will be performance concern if there are thousands of Block_Line elements. But that is probably the same with FindInArray in your script.
