Precautions for Print Output
If XML code is reformatted with an automatic indenter, output may be affected if print instructions have been written without the precaution of activating the trim attribute. This is due to the fact that the content of the print tag includes the XML CDATA section and, as a result, all internal content.
Copy
<xsql-script>

<set name='x'>Hello</set>
<!-- suspectible to fail if formatted -->
<println><x/></println>

<!-- formatted, the value contains a previous line, subsequent lines, and unwanted indenting -->
