How to use regular expressions?

[nkrgupta]

Hi,

I'm trying to display a value after evaluating it with a regular expression. However I'm not sure what is the right way to do that, and hence not getting results. Following is the code I'm using in XML part of the jrxml.

 

<textFieldExpression><![CDATA[(
 

($F{name}.matches(^.*s-)) ?
(
$F{name}.substring(0,12) + "..."
)
:
($F{name})

)]]></textFieldExpression>

Any help would be much appreciated!

Thanks

I assume what you wanted to do is:

$F{name}.length() >= 12 ? $F{name}.substring(0,12) + "..." : $F{name}

Perhaps you have to do an additional check, if "name" is not null first.

I see regex as somehow possible but less efficient and overflow here. But the regex expression would be:

$F{name}.matches("^.{12,}$") ? $F{name}.substring(0,12) + "..." : $F{name}

Of course, the null-check remains here as well.

Cheers, Thomas
