Accessing the “Bulk modify contents” panel

In your “Site setup” section you will find a new “Bulk modify contents” panel. All operations take places from this page.

Basic search

The upper section of the page is about searching contents.

You must select which content types you want to inspect by checking the “Content types” section. Although this selection display all content types, note that only a subset of them usable (for example: the Link content types is not using any text field right now).

This selection will trigger a catalog search of all types in the selection (so keep this selection at minimum).

The most important field is the “Search regex”, where you must write a regular expression. For every content type found, it’s text field will be loaded and text inside wil be parsed for searching matches with the regex.

You can change some regex search configuration option using the “Regex flags” set of checkboxes.

Now you can hit the search button below.

Results

Results of the search are displayed in a table at the bottom of the page.

The table will contain a preview of the found text and minimal information about the content. Please note that a single document can be found multiple time in the table as the minimal entity is the text match, not the document itself.

Replace text

The simpler way of performing text replacement is get filling the “Default replacement” text area.

The table of results will change, providing a graphical preview of what will be changed applying your replacement expression.

The user must now select all replacement that he really want to apply, the click the “Modify selected” button. Only selected matches are changed.

Replacing options

When changing text you are (obviously) changing a Plone content, so you have some additional option available:

Do not update anything (silent change)

Useful you you want to fix some contents without updating other metadata from the content itself. Only the text field (and the Plone full text index) will be updated).

Site members will never notice this tpe of changes.

Update modification time

Update also the last modification time of the document.

Create a new version (if possible)

Full modification. If the content type is versionable, a new version will be saved.ù

Advanced server side operations

Sometimes a simple text regex expression is not enough. This product is supporting a way of handling really complex text substitution by calling some server side components.

By default, only one handler is available: “Convert internal links to resolveuid usage”, that can transform Plone internal links to content to a form that use the “resolveuid” call. This can be used in Plone sites where the TinyMCE option “Link using UIDs” were not enabled by mistake (something like the feature given by Kupu editor).

Adding new server side special handlers

Proving new IBulkModifyReplacementHandler utility will automatically display new special replacement:

<utility
     name="handler_name"
     component="your.product.utility.YourTextSpacialReplacement"
     provides="rt.bulkmodify.interfaces.IBulkModifyReplacementHandler"
  />

Extending handled types

To being able to change a text field of a type not handled, you must provide a proper adapter with a 3rd party product:

<adapter
      for="your.product.interfaces.IYourContentTypeInterface"
      provides="..interfaces.IBulkModifyContentChanger"
      factory="your.product.adapter.YourTextContentAdapter"
      />
