Warning: DOMDocumentFragment::appendXML() when input is not normalized

Open on Drupal.org →
Created on 9 October 2024, about 1 month ago

When HTML input is not properly normalized, many XML errors can result. This is appearing when using the accordion component as part of the uswds_ckeditor_integration → module, which switched from ckeditor5_embedded_content to embedded_content in the most recent release.

Example error:

Warning: DOMDocumentFragment::appendXML(): ^ in Drupal\embedded_content\Plugin\Filter\EmbeddedContent->process() (line 104 of /app/web/modules/contrib/embedded_content/src/Plugin/Filter/EmbeddedContent.php)

    I'm not sure if this should be the responsibility of the embedded_content module or the plugin creating the markup.

    However I would like to be able to reproduce the issue on my local environment: Could you provide the exact steps to reproduce this issue, with module version numbers, themes and modules installed,

    Thanks!

    Drupal 10.3.6
    'drupal/uswds_ckeditor_integration:3.0.2'
    'drupal/embedded_content:2.0.1'

    Basic HTML text format uses Embedded Content in CKEditor.

    1. Create a new node (Basic Content)
    2. Click the "Embedded Content" button in the CKEditor toolbar
    3. Select "Accordion" for content type
    4. Enter a heading and body, click "Embed"
    5. Save the new node
    6. Errors appear (see screenshot)
