| For loop question | For loop question 2007-06-29 - By broken connection
Wow..now thats too much code for me!!!!!
I don't want something that complex,is this the only way to accomplish this
or some simpler way is also there, I was thinking of something like this:
<for list="${pass1.property},${pass2.property},${pass3.property}"
param="argvalue">
<sequential>
<exec executable="${ext}" >
<arg value="/c"/>
<arg value="execute.bat @{argvalue}"/>
<redirector outputproperty="result.property" />
</exec>
</sequential>
</for>
<if>
<equals arg1="${pass1.property}" />
<then>
<echo>"Do your stuff here for property1" />
</then>
</if>
.....
.....
.....
If not,I would try to understand your code,modify it and use for my needs.
Thanks Again.....
