XmlDataProcessor (engine/dataprocessor)

@ckeditor/ckeditor5-engine/src/dataprocessor/xmldataprocessor

class
See source

The XML data processor class. This data processor implementation uses XML as input and output data. This class is needed because unlike HTML, XML allows to use any tag with any value. For example, <link>Text</link> is a valid XML but invalid HTML.

Filtering

Properties

  • namespaces : DOMParser

    A list of namespaces allowed to use in the XML input.

    See source

    For example, registering namespaces [ 'attribute', 'container' ] allows to use <attirbute:tagName></attribute:tagName> and <container:tagName></container:tagName> input. It is mainly for debugging.

  • _domConverter : DomConverter

    private

    DOM converter used to convert DOM elements to view elements.

    See source

  • _domParser : DOMParser

    private

    DOM parser instance used to parse an XML string to an XML document.

    See source

  • _htmlWriter : BasicHtmlWriter

    private

    A basic HTML writer instance used to convert DOM elements to an XML string. There is no need to use a dedicated XML writer because the basic HTML writer works well in this case.
