Hi all,

I am trying to write an XML with optional attributes. If the attribute is null or missing I don't want to have it in the output xml. I xml attributes, not child elements. When using the regular xml writer, all fme attributes are redirected as child elements and missing attributes are properly removed.

However, when using xml attributes within a xml templater, missing attributes are still there and note removed.

Any idea on how to solve this?

I've had the same issues, which for my specific task I was able to solve using two StringReplacers with the following regular expressions:

<[a-zA-Z0-9_]+>\s*</[a-zA-Z0-9_]+>

This one removes emtpy tags, e.g. "<tag></tag>"

And to remove emtpy self-closing tags, such as "<tag />":

<[a-zA-Z0-9_]+/>

I don't think it's ideal, but at least it works. I'd be glad if someone with a more elegant solution would like to share it here.

Edit: Oh, and I forgot to mention that I'm using the XMLTemplater and not the XML Writer!
