[Very simple newbiequestion] Selecting childnodes with foreach and apply templates.
I have an XML which looks like this:
<dvdcollection>
<dvd id="1">
<title>Text</title>
<releasedate>Text</releasedate>
<runningtime>Text</runningtime>
<rating>Text</rating>
<actors>
<actor>Text</actor>
<actor>Text</actor>
<actor>Text</actor>
</actors>
</dvd>
</dvdcollection>
I'm presenting the data in a simple html-table with XSLT and want to print all the actors in one <td> with <br /> after each i use this XSLT:
<xsl:template match="actors">
<xsl:for-each select=".">
<xsl:value-of select="actor"/><br />
</xsl:for-each>
</xsl:template>
and in a for-each loop I use <td><xsl:apply-templates select="actors"/></td> as the tutorial on apply-templates on w3schools shows. I can display the title and other elements by just using <xsl:value-of select="title"/> but with this code I only get the first <actor> element in the tree. :(
What am I missing?
Ive tried having two foreach loops inside eachother but that didn't work and I've heard apply-templates is better in many ways. Please help.
Re: [Very simple newbiequestion] Selecting childnodes with foreach and apply template
Code:
<xsl:for-each select=".">
"." selects the current node, so you are running a for-each on the set of nodes that contains only the current node. But the current node is just one node, and it's already the current node, so the for-each does exactly nothing and might as well be removed.
Code:
<xsl:value-of select="actor"/>
At the point you have this line actors is the current node, so "actor" selects all three actor elements. But value-of is a only accepts a single node, so it just uses the first of the three selected nodes.
Better would be to replace the for-each with an apply-templates on the actor elements
Code:
<xsl:apply-templates select="actor"/>
And make a template for actor
Code:
<xsl:template match="actor">
<xsl:value-of select="text()"/>
<br/>
</xsl:template>

Thanks for clearing that up. My finished xsl looks like this and works like a charm.

Re: [Very simple newbiequestion] Selecting childnodes with foreach and apply templates.
Hi ..
I have the following problem regarding childnodes and xsl:for-each select
My XML looks like this :
Code:
<DATA>
<CASE>
<INSTRUCTION Type="Deleted">
<OPERATION>Blah blah</OPERATION>
<FEEDBACK>feedback1</FEEDBACK>
<FEEDBACK>feedback2</FEEDBACK>
<FEEDBACK>feedback3</FEEDBACK>
<FEEDBACK>feedback4</FEEDBACK>
<FEEDBACK>feedback5</FEEDBACK>
<TIME>time blah bah</TIME>
</INSTRUCTION>
<INSTRUCTION Type="Stable">
<OPERATION>Blah blah</OPERATION>
<FEEDBACK>feedback1</FEEDBACK>
<FEEDBACK>feedback2</FEEDBACK>
<FEEDBACK>feedback3</FEEDBACK>
<FEEDBACK>feedback4</FEEDBACK>
<FEEDBACK>feedback5</FEEDBACK>
<TIME>time blah bah</TIME>
</INSTRUCTION>
<INSTRUCTION Type="Modified">
<OPERATION>Blah blah</OPERATION>
<FEEDBACK>feedback1</FEEDBACK>
<FEEDBACK>feedback2</FEEDBACK>
<FEEDBACK>feedback3</FEEDBACK>
<FEEDBACK>feedback4</FEEDBACK>
<FEEDBACK>feedback5</FEEDBACK>
<TIME>time blah bah</TIME>
</INSTRUCTION>
</CASE>
</DATA>
And I basically want to use XSLT to represent this data in X-HTML format.
Code:
<xsl:for-each select="Instruction[@Type !='Stable']">
<xsl:choose>
<xsl:when test="@Type = 'Deleted'">
<tr>
<td class="delete_l">
Instruction <xsl:value-of select="@Type"/>
</td>
<td class="delete_r">
<br/>
</td>
</tr>
<tr>
<td class="delete_l">
<br/>
</td>
<td class="delete_r">
<xsl:for-each select=".">
<xsl:value-of select="."/>
</xsl:for-each>
</td>
</tr>
</xsl:when>
<xsl:otherwise>
<tr>
<td>
Instruction <xsl:value-of select="@Type"/>
</td>
<td>
<xsl:value-of select="@Type"/>
</td>
</tr>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
The output is the nodes Operation+Feedback+Time in a cell, which i really do not understand.
I actually want the results to come out one by one, and each node in one cell..
Or at least being able to put a line break between them :(
Can someone help me along with this please ??
Re: [Very simple newbiequestion] Selecting childnodes with foreach and apply templates.
Sorry for taking up your time. I just found out that I could use a couple of templates in series :(
I'm kindly asking the admin to remove my post please ...
Thanks a lot and sorry again ...
