class DomSelect in Migrate Plus 8.5

Select strings from a DOMDocument object.

Configuration:

  • selector: An XPath selector that resolves to a string.
  • limit: (optional) The maximum number of results to return.

Usage:


process:
  bar:
    -
      plugin: dom
      method: import
      source: text_field
    -
      plugin: dom_select
      selector: //img/@src

This example will return an array of the src attributes of all <img> tags in the source text. Add 'limit: 1' to return at most one result.
