Transformer Factory options

Most of the use cases I have seen with this class is modifying links: 

https://sling.apache.org/documentation/bundles/output-rewriting-pipelines-org-apache-sling-rewriter.html

What comments are you referring to? 

We have something like this:

...

<!-- add="ASSOCIATE_1"
 <div class="image parbase section">
  <img src="/content/business/test-pages/components/abc/image.img.png" alt="image" class="img-responsive"/>
 </div>
-->
...

So we comment out the html for certain associates.  They can then uncomment and use accordingly ....

I want to use the Transformer Factory to change the following

original : <img src="/content/business/test-pages/components/abc/image.img.png" alt="image" class="img-responsive"/>

desired output :  <img src="/business/test-pages/components/abc/image.img.png" alt="image" class="img-responsive"/>

However, since it's part of a comment it does not get picked up for processing.

Any thoughts?

HI Dean - i have not personally heard about using the Transformer to modify comments in code like this., I will check within Adobe. 

Hi,

This would theoretically be possible but it requires your Transformer implement the characters() method and parse the contents of that text yourself. If the contents of these comments are regular, you might be able to handle this with regex, but if the HTML is "normal" HTML, it is far from regular enough to be handled in this way.

If you are going to go down this path, I'd highly recommend paying attention to slides 19 through 22 of http://www.slideshare.net/justinedelson/mastering-the-sling-rewriter (blatant self-promotion)

Justin,

I'm open to trying anything ...

When I print out the attributes in the startElement method, I never see the comments. 

Is it just ignoring them?

The contents of the comments are extremely regular ... I'd like to be able to use regex.

I've reviewed the slides but I'm still not sure how I can change these things without the comments coming into the transformer.

Thanks,

-Dean

Justin,

I've added code to the Transformer, but I'm still not able to see the comments in the transformer.

<!-- add="ASSOCIATE_1"
  <div class="image parbase section">
   <img src="/content/business/test-pages/components/abc/image.img.png" alt="image" class="img-responsive"/>
  </div>
-->

Any suggestions on how to implement the characters() method to obtain the comments is GREATLY appreciated?

Thank you for all your help.

Right, like I said, you wouldn't see the commented elements in the startElement(). You will see them (as text) in the characters() method. startElement() is useless for this use case as those aren't actually elements. They are text (character data in XML parlance).
