Error when using the tcmse:PublishBinary in XSLT TBB with the XSLT Mediator

Question

I am working on XSLT TBB in SDL Tridion 2011 SP1. I am using XSLT mediator downloaded from Tridion site.

I have created a TBB to retrieve the image as follows:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:simple="uuid:c5e80ef4-9afd-421a-9205-d5af4c9f2c5c" 
    xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:tcm="http://www.tridion.com/ContentManager/5.0"
    xmlns:tcmse=”http://www.tridion.com/ContentManager/5.1/TcmScriptAssistant”
    exclude-result-prefixes="msxsl simple">

    <xsl:output method="xml" indent="yes" omit-xml-declaration="yes" />

    <xsl:template match="/">
        <xsl:element name="p">
            <xsl:apply-templates select="tcm:Component/tcm:Data/tcm:Content/simple:Content"/>
        </xsl:element>
    </xsl:template>

    <xsl:template match="simple:Content">
        <xsl:element name="img">
            <xsl:attribute name="src">
                <xsl:value-of select="tcmse:PublishBinary(string(simple:photo/@xlink:href)))"/>
            </xsl:attribute>
        </xsl:element>
    </xsl:template>
</xsl:stylesheet>

I am getting error as

  [CDATA[Unable to retrieve rendered data from Component Presentation.]]>
</tcm:Line>
<tcm:Line ErrorCode="80040000" Cause="true">
    <![CDATA[
     Cannot find a script or an extension object associated with namespace
     'http://www.tridion.com/ContentManager/5.1/TcmScriptAssistant'.]]

I understood that problem is due to 'http://www.tridion.com/ContentManager/5.1/TcmScriptAssistant'.

Can any one suggest the modifications needed to overcome it?

DO I need to change any thing in TBB or Component Template.

Thank you.

tcmse:PublishBinary is not implemented by the XSLT Mediator. This is a function of the default XSLT Template engine, not the Mediator engine.

To publish binaries with the XSLT Mediator you do something like this:

<xsl:element name="img">
  <xsl:attribute name="src">
    <xsl:value-of select="simple:image/@xlink:href"/>
  </xsl:attribute>
</xsl:element>

Then make sure you use the Default Finish Actions, or at least the "Extract Binaries from HTML" and the "Publish Binaries In Package" TBBs

The XSLT Mediator allows you to add new methods to the XSLT Extension object, you can find it in the 'XSLT Template Helper' class available in the XSLT Mediator package.

In order to use it you will need to add the "http://www.sdltridion.com/ps/XSLTHelper" namespace in your XSLT template like xmlns:ext="http://www.sdltridion.com/ps/XSLTHelper".

A sample of how a PublishBinary method would is shown below.

public string PublishBinary(string tcmUri)
{
  Component mComponent = new Component(new TcmUri(tcmUri), session);
  Binary binary = engine.PublishingContext.RenderedItem.AddBinary(mComponent);
  return binary.Url;
}

public string PublishBinary(string tcmUri, string sgTcmUri)
{
  Component mComponent = new Component(new TcmUri(tcmUri), session);
  StructureGroup sg = new StructureGroup(new TcmUri(sgTcmUri), session);
  Binary binary = engine.PublishingContext.RenderedItem.AddBinary(mComponent,sg);
  return binary.Url;
}

you can use those methods like this.

<xsl:element name="img">
    <xsl:attribute name="src">
        <xsl:value-of select="ext:PublishBinary(string(@xlink:href))" />
    </xsl:attribute>
</xsl:element>

Thank you for the answer. If possible can you provide the code for RenderComponentPresentation method also. One small doubt. I need to add the mentioned namespace in the XSLT TBB only now. — Patan, Jun 08 '12 at 04:35
Yes, you just need to add the mentioned namespace. Note that in my code samples I am using the engine, package and session objects, since the XSLT Mediator is open source you may need to modify it a little bit to add those properties to the helper. — Eric Huiza, Jun 12 '12 at 18:16
