Hi, Jay,
ok, here more details:
my XML source looks like that:
...
<object Level="0">
<relation Level="0">
<object Level="1">
<relation Level="1">
<object Level="2">
...
</object>
</relation>
</object>
<object Level="1">
<relation Level="1">
<object Level="2">
...
I think you got the structure. There are <attribute> elements and a lot of
element attributes I now haven't shown because not needed for my question.
I have to create a explorer tree like picture from that. For each line of my
list I need to find out what tree structure images are needed (&u2503;
&u2523; &u2517; in form of fixed size gif images), I need to know for
example if this element is the last child of its parent, if the parent is
the last child of its parent and so on, to decide which image is the
correct.
I need it recursive because there is theoretical no limit of depth,
practical it would lie at about ten.
My solution was about this:
<xsl:template match="object">
<tr>
<td>
<xsl:call-template name="tree-scructure">
<xsl:with-param name="treenode" select="node()"/>
</xsl:call-template>
<xsl:value-of select="[EMAIL PROTECTED]'DisplayedName']/value"/>
</td>
<td>
<xsl:call-template name="replace-null">
<xsl:with-param name="input"
select="[EMAIL PROTECTED]'beGTABeschreibPos']/value"/>
</xsl:call-template>
</td>
<td>
<xsl:value-of select="attribute
[EMAIL PROTECTED]'LifeCycleState']/value"/>
</td>
<td>
<xsl:value-of select="[EMAIL PROTECTED]'ProjectName']/value"/>
</td>
</tr>
<xsl:apply-templates select="relation"/>
</xsl:template>
<xsl:template match="relation">
<tr>
<td>
<xsl:call-template name="tree-scructure">
<xsl:with-param name="treenode" select="node()"/>
</xsl:call-template>
<xsl:value-of select="[EMAIL PROTECTED]'LDisplayedName']/value"/>
</td>
</tr>
<xsl:apply-templates select="object"/>
</xsl:template>
<xsl:template name="tree-scructure">
<xsl:param name="treenode"/>
<xsl:param name="recursive"/>
<xsl:if test="$treenode/@Level > 0">
<xsl:call-template name="tree-scructure">
<xsl:with-param name="treenode" select="parent::node()"/>
<xsl:with-param name="recursive">true</xsl:with-param>
</xsl:call-template>
</xsl:if>
<img width="16" height="16" alt="just an incomplete test"/>
</xsl:template>
That's where I am now.... a not working thing.
Thank you for your time,
Kai
