Question

I need to display few values based on if condition in the birt report.Is there any way to do that?
I’m using XML as a datasource, so if the tag is not empty i want to display it within the report.

this is the xml sample i need to add within my report

<wr:if><wr:out/></wr:if><wr:if><wr:out/></wr:if><wr:if><wr:out/></wr:if>

here the <wr:out/> corresponds to a tag in XML which i’ve used as a dataset.

I want to know how to display these data within the birt report?

Answer 1

you can assign the property visibility

<list-property name="visibility">
  <structure>
     <property name="format">all</property>
     <expression name="valueExpr" type="javascript">your evaluation here</expression>
  </structure>
</list-property>

When expression evaluates to true the the element is hidden.
