accessing an item without knowing its name

consultant1

I have a DCT in which the item's name is dynamically built by a perl script based on the occurence of DCRs of a different datatype. Now my problem is the number of items and their name is not known. How do i access them in my presentation template?I have to access the name of the item also any suggestions please...?

You can do a number of things.

You can read the whole DCR into a perl variable and parse out each element's name one at a time using an XML tokenizer. Then use the iw_perl function iwpt_dcr_value (see below)

If you know what the possible names could be you could either put a bunch of "<iw_if ...value exists>" or if the names flow along a date type syntax you could dynamically retrieve the information using perl to build the names for you. For example:

<iw_perl><[!CDATA[
$dcrvaluename = "pressrelease_$mm$dd$yy";
iwpt_output(iwpt_dcr_value($dcrvaluename));
]]>
</iw_perl>
