Formating the wcmListElement Link?

Question

I would like to append a url query string parameter to the end of a url/link
that is part of a static list.
My static list has two elements: myID and myLink
For example, here's what my static list data file looks like:
<wcm:list name="myStaticList">
<wcm:row>
<wcm:element name="myID">12345</wcm:element>
<wcm:element name="myLink"><a
href="[!--$wcmUrl('link','myDatafile1')--]">Product 1</a></wcm:element>
</wcm:row>
<wcm:row>
<wcm:element name="myID">22222</wcm:element>
<wcm:element name="myLink"><a
href="[!--$wcmUrl('link','myDatafile2')--]">Product 2</a></wcm:element>
</wcm:row>
</wcm:list>
Here is my Region Template script that loops through the static list:
<!--$wcmListStart("myStaticList")-->
<!--$wcmListIndex = 0-->
<!--$wcmListNumRows = wcmListRowCount()-->
<table border=1>
<!--$loopwhile wcmListIndex < wcmListNumRows-->
<tr>
<td><!--$wcmListElement("myID", wcmListIndex)--></td>
<td><!--$wcmListElement("myLink", wcmListIndex)--></td>
</tr>
<!--$wcmListIndex = wcmListIndex + 1-->
<!--$endloop-->
</table>
<!--$wcmListEnd("myStaticList")-->
I want to dynamically append the myID number to the end of the myLink url. So
that for example my final link would look like this:
http://myserver.com/site/myDatafile1?id=12345
The data files for this list fall into a replaceable region on the secondary
layout page which uses a custom component on part of it to run a query based on
the incoming id. So I need the id on the url.
What I'm trying to do seems simple, but I'm not sure how to do this. This is on
Site Studio 10gR4.

You need to do something slightly fancy, there... The element "myLink" is stored as HTML, something like this:
&lt;a href="http://server/foo/bar"&gt;Product 1&lt;/a&gt;
So... in order to make this work, you need to do some search-and-replace... Something like this should be close:
<!--$myID = wcmListElement("myID", wcmListIndex)-->
<!--$myLink = wcmListElement("myLink", wcmListIndex)-->
<!--$myNewLink = strReplace(myLink, "\"&gt;", "?id=" join myID join "\"&gt;")-->
<!--$myNewLink-->
You get the picture... replace the end-quote and end-angle-bracket with your parameter and then re-close with and end quote and angle bracket.
