<webm:loop>

You can use the <webm:loopsep> tag to insert a specified character sequence between results from a <webm:loop> tag in the HTML page produced from the JSP. (<webm:loopsep> does not insert the character sequence after the result produced by the last iteration of the loop.)

For this data structure...	Integration Server loops over…
Pipeline	Each key in the pipeline.
Document	Each key in the Document.
Document List	Each Document in the Document List.
String List	Each String in the String List.

Argument	Description
[variable="loop_variable"]	Document, Document List, or String List to loop over. If you do not specify this option, Integration Server loops over the entire pipeline. Example <webm:loop variable="items">
[loopStruct="true"]	Tells Integration Server to loop over each key in the pipeline, Document, Document List, or String List. Example <webm:loop variable="items" loopStruct="true"> If you want to dynamically access the names of the keys in the structure over which you are looping, use the predefined $key keyword. If you have nested loops and the outer loop is looping over a structure whose contents are dynamic, and you want the inner loop to loop over the keys in the current key of the outer loop, set variable in the inner loop to #$key keyword. You most often use this keyword to process a set of Documents contained within another Document. For an example of using these keywords, see the “Examples” section, below.
[excludePrivate="true"]	Tells Integration Server to skip keys whose names begin with $. Example <webm:loop variable="items" excludePrivate="true">

This shipment contains the following items:
<webm:loop variable="items">

<webm:value variable="qty"/>
<webm:value variable="stockNum"/>
<webm:value variable="description"/>
<webm:value variable="status"/>

</webm:loop>

This code loops over the keys in the Document named Addresses, whose contents are not known until run time, and inserts each name and its associated address into the HTML page produced from the JSP. The basic structure of the Document looks like this:

Key	Value
Global Sporting Goods, Inc.	Key	Value
	streetAddr1	10211 Brookpark Road
	streetAddr2
	city	Cleveland
	state	OH
	postalCode	22130
Fitness Shoes	Key	Value
	streetAddr1	2549 Oak Avenue
	streetAddr2
	city	Silver Spring
	state	MD
	postalCode	20905

Key	Value
Yoga Wear	Key	Value
	streetAddr1	6666 Maple Street
	streetAddr2	Suite 100
	city	New York
	state	NY
	postalCode	11302

Customer Addresses:

<webm:loop variable="Addresses" loopStruct="true">
<webm:value variable="$key"/>
<webm:loop variable="#$key" loopStruct="true">
<webm:value variable="streetAddr1"/>
<webm:value variable="streetAddr2"/>
<webm:value variable="city"/>
<webm:value variable="state"/>
<webm:value variable="postalCode"/>
</webm:loop>
</webm:loop>
