    Hi,

    I hope someone can help. I am trying to build a delimited list (delimited by |) to a temporary file with the following code:

    <loop item="professionList" index="j">
    <list>
    <xpath expression="(//div&lt;span&gt;[@class='categories']&lt;/span&gt;//li/text())">

    </xpath>
    </list>
    <body>

                        <file action="append" type="text" path="professionList.txt">                            
                        <template>
                            <case>
                                <if condition="${j = 1}">
                                    ${professionList}
                                </if>
                                <else>
                                    ${professionList}
                                </else>
                            </case>
                        </template>
                    </file>
                </body>
            </loop>

    The problem that I'm having is that the if condition determined by the loop counter j always branches to else even though as I understand this the first pass through the loop should match ${j = 1}. Can someone please explain why?

    Found a soultion to my problem by capturing the count of list items in a separate var and then comparing to the loop index var using the toInt() method on both the count of list items var and the loop index var.

    <case>
    <if condition="${ListCount.toInt() != j.toInt()}">
        ${List}|
    </if>
    <else>
        ${List}
    </else>
</case>
