John PapadopoulosSubject: Relational Database Hierarchical (flat) table to XML Tree Mapping.

Hi,
I have a hierarchical table in a relational database. The table structure is:

id, description, parent_id.

How can I map it (create child elements) to an XML tree using Stylus Studio? Any screencasts?

I guess what you want to do is to convert that table into a hierarchical XML; you should be able to do something like this (using the proper table information in XQuery):


declare function local:getChildren($node as element(*,xs:anyType))
{
for $child in collection("pubs.dbo.hierarchy")/hierarchy[number(parent_id) = number($node/id)]
return
<item id="{$child/id}">
<value>{$child/description/text()}</value>
{local:getChildren($child)}
</item>
};


<items> {
for $roots in collection("pubs.dbo.hierarchy")/hierarchy[not(parent_id)]
return
<item>
<value>{$roots/description/text()}</value>
{local:getChildren($roots)}
</item>
} </items>
