ModX how to change the output of a parameter in a chunk?

Question

MODX

Hello. ModX don't know at all how to make the output changed. For example, I write like this.
data-trans=""
Everything is displayed as it should, only in the html parameter the image code, how can I control the output? Remove html tags there or display somehow only the name of the image file. In transmission Is
<img src='/sdfsdf/sdfsdf/aaa.jpg'>
it possible to somehow parse the string before output? Thank you.

And why is the output in the form of an HTML code of the picture not satisfied?
The string can be modified to some extent using Output Filters:
