Hi,
I am trying to use locateblock to get value from xhtml/DD block. Could you please provide me script to achieve this.
My Block

<?xml version="1.0" encoding="UTF-8"?>
<system-data-structure>
    <image1 type="file">
        <content />
        <path>/images/accreditation.jpg</path>
        <dynamic-metadata>
            <name>display-in-nav</name>
            <value>Yes</value>
        </dynamic-metadata>
        <link>site://root/images/accreditation.jpg</link>
        <site>root</site>
        <name>accreditation.jpg</name>
    </image1>
    <image2 type="file">
        <content />
        <path>/images/accreditation.jpg</path>
        <dynamic-metadata>
            <name>display-in-nav</name>
            <value>Yes</value>
        </dynamic-metadata>
        <link>site://root/images/accreditation.jpg</link>
        <site>root</site>
        <name>accreditation.jpg</name>
    </image2>
    <image3 type="file">
        <content />
        <path>/images/accreditation.jpg</path>
        <dynamic-metadata>
            <name>display-in-nav</name>
            <value>Yes</value>
        </dynamic-metadata>
        <link>site://root/images/accreditation.jpg</link>
        <site>root</site>
        <name>accreditation.jpg</name>
    </image3>
</system-data-structure>

My format

#set ( $imageUploader = $_.locateBlock("/news/imageuploader",$currentPageSiteName )) ## Successfully loaded
How do I navigate from here and fetch <link> node value ?

Thanks,
Prashanth

    Since you have chosen to use the Locator tool, the block XML is no longer available to you. Instead, you need to work with structured data. See my discussion on Accessing system-data-structure with the Locator Tool.

    I am also working on Lesson 10: Structured Data and Metadata, taking about this, in my tutorial site.

    Hi Prashanth,

    As Wing mentioned, you will need to use the Cascade API to access your Block's structured data. In your case the following would give you access to each individual file chooser:

    • $imageUploader.getStructuredDataNode("image1")
    • $imageUploader.getStructuredDataNode("image2")
    • $imageUploader.getStructuredDataNode("image3")

    Alternatively, you could loop over all of the nodes assuming you need to access each of the choosers and the block's data definition won't be changing:

    #foreach ( $imageField in $imageUploader.structuredData)
      #if (!$_PropertyTool.isNull($imageField.asset))
        $imageField.asset.link
      #end
    #end
    

    Please let me know if you have any questions.

    Thanks!

    Thank you Wing & Ryan. It worked.
    To get <link> value, I used,

    $imageUploader.getStructuredDataNode("image1").asset.link
    $imageUploader.getStructuredDataNode("image2").asset.link
    $imageUploader.getStructuredDataNode("image3").asset.link

    (foreach loop also worked as Ryan suggested)

    Thanks,
    Prashanth
