Glenn MeadowsSubject: Creating a XML document with nested nodes
Author: Glenn Meadows
Date: 25 Aug 2006 05:25 PM
Hello,

Using XSLT and the mapper utility with Stylus Studio, I have created a XML document with a list of 2 fields being TASK_NAME and TASK_OUTLINE_LEVEL. The TASK_NAME is just that, the description of a task. The TASK_OUTLINE_LEVEL indicates the hierarchy of each task in a tree structure with 0 being the top-most node and 1, 2, 3, etc. being nodes further inside the tree.

I have attached a source XML file and the XSLT file that renders output to a target XML file.

I am doing a eval of SS and so I am new at all this. Could someone tell me if this is achievable?

Thanks,
- Glenn

My XML file did not get attached to the first message, so here it is.

Thought I might add some additional clarity as to what I am looking for.

A target XML file with a tree structure defined as follows;

<node1>Summary Task
<node2>task1</node2>
<node3>task2
<node4>task3</node4>
<node5>task4</node5>
</node3>
<node6>task5</node6>
</node1>

which would allow a tree control to be populated with this tree structure;

Summary Task
task1
task2
task3
task4
task5

Glenn,
you can try code similar to the following; I'm assuming that the position of the nodes in the document is what is determinint the parent/child relationship, as long as the outline-level data.

<?xml version='1.0' ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/">
<dataroot xmlns:od="urn:schemas-microsoft-com:officedata" xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance">
<xsl:for-each select="dataroot/MSP_TASKS[not(TASK_OUTLINE_LEVEL)]">
<!-- what to do with tasks with no outline level (and no name)? -->
</xsl:for-each>
<xsl:for-each select="dataroot/MSP_TASKS">
<xsl:if test="TASK_OUTLINE_LEVEL=1">
<node name="{TASK_NAME}">
<xsl:call-template name="getChildren">
<xsl:with-param name="level" select="2"/>
<xsl:with-param name="fromPosition" select="position()+1"/>
</xsl:call-template>
</node>
</xsl:if>
</xsl:for-each>
</dataroot>
</xsl:template>

<xsl:template name="getChildren">
<xsl:param name="level"/>
<xsl:param name="fromPosition"/>
<xsl:choose>
<xsl:when test="/dataroot/MSP_TASKS[$fromPosition]/TASK_OUTLINE_LEVEL = $level">
<node name="{/dataroot/MSP_TASKS[$fromPosition]/TASK_NAME}">
<xsl:call-template name="getChildren">
<xsl:with-param name="level" select="$level+1"/>
<xsl:with-param name="fromPosition" select="$fromPosition+1"/>
</xsl:call-template>
</node>
<xsl:call-template name="getChildren">
<xsl:with-param name="level" select="$level"/>
<xsl:with-param name="fromPosition" select="$fromPosition+1"/>
</xsl:call-template>
</xsl:when>
<xsl:when test="/dataroot/MSP_TASKS[$fromPosition]/TASK_OUTLINE_LEVEL > $level">
<xsl:call-template name="getChildren">
<xsl:with-param name="level" select="$level"/>
<xsl:with-param name="fromPosition" select="$fromPosition+1"/>
</xsl:call-template>
</xsl:when>
</xsl:choose>
</xsl:template>

</xsl:stylesheet>
