XSL/XML Issue - Attribute and namespace issue

Question

I am using ThumbGen to generate Movie Sheets. For my digital movies. It uses XSL. and my idea was to have it take the 'actors' and load the picture up from a folder with their pics in it. I searched online, and someone else had a question on how to fix an issue doing the exact same thing. So I used that as a basis, but was unable to get it to work.

I'm getting the error: "Attribute and namespace nodes cannot be added to the parent element after a text, comment, pi, or sub-element node has already been added."

In my trying to get this to work I found this:

https://social.msdn.microsoft.com/Forums/en-US/f83fa128-2d0d-4bdc-bfe1-26fbaf6159c7/xsl-and-xml-with-thumbgen

And using that, his 'fix' that was told to him, is giving me the error he was having before the fix, I've been working on it for the past week. but I've never even heard of XSL before this. Can anyone see maybe what's wrong with it?

But here is the Line in the XML File:

<ImageElement Name="Actor1" X="980" Y="44" Width="93" Height="123" Source="File" Offset="0" MultiPageIndex="-1" SourceData="" NullImageUrl="%PATH%\..\Common\cast\NoPhotoAvailable.jpg" />

Ok I've updated the XSL file To:

 <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
    <xsl:variable name="pathvalue" select="//tokens/token[@name='%PATH%']"/>
    <xsl:variable name="folderactors" select="string('\..\Common\cast\')"/>
    <xsl:variable name="actorsext" select="string('.jpg')"/>
    <xsl:variable name="actorstext" select="string('')"/>
    <xsl:variable name="lista1" select="//tokens/token[@name='%ACTORS%']"/>
    <xsl:variable name="actor1" select="substring-before($lista1, ',')" />  
    <xsl:variable name="resto1" select="substring-after($lista1, ',')" />
    <xsl:variable name="lista2" select="$resto1"/>
    <xsl:variable name="actor2" select="substring-before($lista2, ',')" />
  <xsl:template match="ImageElement[@Name='Actor1']">
        <xsl:copy>
            <xsl:apply-templates select="@*"/>
            <xsl:choose>
                <xsl:when test="$actor1 != '' ">
                    <xsl:attribute name="SourceData">
                        <xsl:value-of select="concat($pathvalue,$folderactors,$actor1,$actorsext)"/>
                    </xsl:attribute>
                </xsl:when>
            </xsl:choose>
            <xsl:apply-templates select="node()"/>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

And now i'm getting the error:

Answer 1

You need to define template for attribute nodes, or the xslt processor will use the built-in one, which just output the attribute value as text node (see this previous post for details. Then, when you try to add an attribute to your element, you have several text nodes added previously by all the built-in templates on attributes.

So just add :

<xsl:template match="@*">
      <xsl:attribute name="{name()}" select="."/>
</xsl:template>

You could also just switch the <xsl:apply-templates select='@*'/> by :

<xsl:copy-of select="@*"/>

Which will do the job directly.

If you have more inputs elements, you may need to add a default template for elements too, a one like :

<xsl:template match="*">
    <xsl:copy>
        <xsl:apply-templates select='@* | node()'/>
    </xsl:copy>
</xsl:template>

i got it working with:

    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>
   <xsl:template match="ImageElement[@Name='Actor1']">
      <xsl:copy>
            <xsl:apply-templates select="@*"/>
            <xsl:choose>
                <xsl:when test="$actor1 != '' ">
                    <xsl:attribute name="SourceData">
                        <xsl:value-of select="concat($pathvalue,$folderactors,$actor1,$actorsext)"/>
                    </xsl:attribute>
                </xsl:when>
            </xsl:choose>
            <xsl:apply-templates select="node()"/>
            </xsl:copy>

   </xsl:template>
</xsl:stylesheet>

Now i get to see if I make it work with more than actor.
