Custom Publish Trigger

My team and I just made a custom publish trigger, and we were wondering if we could somehow get the string from the contents of a page object after it has been published. For example, here is a simple code snippet of what we would like to do:

String content = clearWhiteSpace(page.getXHTML());

We want to use the clearWhiteSpace method to get rid of extra lines and spaces. Then set the cleaner content to the page again. However, this was returning as null.

Any suggestions?

Thank you!

    The (get|set)XHTML methods are used for Pages that do not have a Data Definition applied to them (ie only contain a Default WYSIWYG). Let me check with the developers to see if this is possible from a Publish Trigger and I will be in touch as soon as I have additional information.

    In the meantime, would you be able to elaborate more on the need to remove the extra whitespace? Is this causing issues or something? Also, do you know where is the whitespace coming from, Velocity Formats perhaps?

    Please let me know if you have any questions.

    Yes, the whitespace is coming from Velocity as far as we know. It isn't causing issues, but whenever we try to download our code to view it or edit it, it has many extra newlines and blank spaces. This program would clean up the code to make it more readable. I have attached an example of the weirdly formatted code that we are returned.

    Thanks for the fast reply!

    Thank you for the additional information and sample file. It definitely looks like you are dealing with whitespace from Velocity Formats, as you indicated.

    Unfortunately, the whitespace coming from Velocity is coming from Velocity itself and not Cascade; however, there are a couple of possible options to help deal with the added whitespace:

    • You can add compression to your webserver so the whitespace is removed when the page is served to the browser. This won't help with your issue of editing the file; however.
    • You can modify your Velocity Formats to remove whitespace using one of these methods
    • You could add apply an XSLT Format at the page, template, or configuration set level which would allow you to modify the rendered HTML before the page is published. Theoretically, you should be able to write XSLT that removes whitespace from the content.

    If you do want to go the publish trigger route, the only way you could accomplish this would be to read the published file from the Destination server after it was published, strip the whitespace, and write the file back to the server. Our .docx publish trigger does something like this where it reads the file from the server, generates a .docx file, and uploads it to the server.

    Please let me know if you have any questions.
