I'm trying to transform xml derived from an MS Project plan. I'm
trying to create a table where each row identifies the resource
(person) assigned to a particular task, but when I loop through the
source, the resource name appears only once. I'm tapped out and tried
everything I can think of. This is a 1.0 stylesheet and I'm using
Saxon 6.5.5
The xml looks like this:
<Project>
<Tasks>
<Task>
<UID>1</UID>
<ID>1</ID>
<Name>Do something</Name>
</Task>
<Task>
<UID>2</UID>
<ID>2</ID>
<Name>Do something else</Name>
</Task>
<Task>
<UID>3</UID>
<ID>3</ID>
<Name>Do everything else</Name>
</Task>
<Task>
<UID>4</UID>
<ID>4</ID>
<Name>A job</Name>
</Task>
<Task>
<UID>5</UID>
<ID>5</ID>
<Name>A biggger job</Name>
</Task>
<Task>
<UID>6</UID>
<ID>6</ID>
<Name>the biggest job</Name>
</Task>
</Tasks>
<Resources>
<Resource>
<UID>1</UID>
<ID>1</ID>
<Name>Tom</Name>
</Resource>
<Resource>
<UID>2</UID>
<ID>2</ID>
<Name>Dick</Name>
</Resource>
<Resource>
<UID>3</UID>
<ID>3</ID>
<Name>Harry</Name>
</Resource>
</Resources>
<Assignments>
<Assignment>
<UID>1</UID>
<TaskUID>1</TaskUID>
<ResourceUID>1</ResourceUID>
</Assignment>
<Assignment>
<UID>2</UID>
<TaskUID>2</TaskUID>
<ResourceUID>2</ResourceUID>
</Assignment>
<Assignment>
<UID>3</UID>
<TaskUID>3</TaskUID>
<ResourceUID>3</ResourceUID>
</Assignment>
<Assignment>
<UID>4</UID>
<TaskUID>4</TaskUID>
<ResourceUID>1</ResourceUID>
</Assignment>
<Assignment>
<UID>5</UID>
<TaskUID>5</TaskUID>
<ResourceUID>2</ResourceUID>
</Assignment>
<Assignment>
<UID>6</UID>
<TaskUID>6</TaskUID>
<ResourceUID>3</ResourceUID>
</Assignment>
</Assignments>
</Project>
My stylesheet looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<xsl:output method="html"/>
<xsl:key name="task" match="Task" use="UID"/>
<xsl:key name="job" match="Assignment" use="TaskUID"/>
<xsl:key name="worker" match="Resource" use="UID"/>
<xsl:template match="/">
<html>
<head></head>
<body>
<xsl:for-each select="//Task">
<xsl:for-each select="key('task',UID)">
<tr>
<td>
<xsl:value-of select="key
('task',UID)/Name"/>
</td>
<td>
<xsl:value-of select="key
('task',UID)/UID"/>
</td>
<td>
<xsl:call-template name="get-uid">
<xsl:with-param name="rid"
select="key('task',UID)/ResourceUID"/>
</xsl:call-template>
</td>
</tr>
</xsl:for-each>
</xsl:for-each>
</body>
</html>
</xsl:template>
<xsl:template name="get-uid">
<xsl:param name="rid"/>
<xsl:call-template name="get-name">
<xsl:with-param name="rid"/>
</xsl:call-template>
</xsl:template>
<xsl:template name="get-name">
<xsl:param name="rid"/>
<xsl:value-of select="key('worker',UID)/Name"/>
</xsl:template>
</xsl:stylesheet>
The results look like this:
<html>
<head>
</head>
<body>
<tr>
<td>Do something</td>
<td>1</td>
<td>Tom</td>
</tr>
<tr>
<td>Do something else</td>
<td>2</td>
<td>Dick</td>
</tr>
<tr>
<td>Do everything else</td>
<td>3</td>
<td>Harry</td>
</tr>
<tr>
<td>A job</td>
<td>4</td>
<td></td>
</tr>
<tr>
<td>A biggger job</td>
<td>5</td>
<td></td>
</tr>
<tr>
<td>the biggest job</td>
<td>6</td>
<td></td>
</tr>
</body>
</html>
I can't figure out why this only retrieves the names the first time
around. I sure would appreciate some help. My thanks in advance.
