Subject [DISCUSS] - XML DSL and trimming value
Date Sun, 20 May 2012 10:33:57 GMT
Hi

We have a number of JIRA tickets which is related
https://issues.apache.org/jira/browse/CAMEL-5294
https://issues.apache.org/jira/browse/CAMEL-5285
https://issues.apache.org/jira/browse/CAMEL-4990

When you use the XML DSLs you may have a coding style where you have
newlines, and spaces etc. in the text of the XML tags, eg

<transform>
  <simple>
    data=${body}
  </simple>
</transform>

Notice how we have new lines in the <simple> text.
Below shows what the intent is without newlines:

<transform>
  <simple>data=${body}</simple>
</transform>

Today we will auto trim Simple expressions (but not the others). IMHO
I think this is wrong and we should make this consistent, to either
- no auto trim
- auto trim all expressions

If we auto trim, and you want an explicit newline, then the end user
can use a \n to indicate newline, eg
<transform>
  <simple>data=${body}\n</simple>
</transform>

I think we should go for a
- auto trim all expressions
- end users can use \n to force new lines

Any thoughts?
