Trim XML whitespace

[ngdias]

I'm getting this:

"#text"
"Options"
"#text"
"Tracks"
"#text"
"Analysis"
"#text"
"Summary"
"#text"

>From looping through a XML node and the Internet tells me the "#text" are
whitespace that can be skipped byt something like  this solution
<http://stackoverflow.com/questions/4650878/how-to-remove-text-from-my-node-parsing-in-java-dom-xml-parsing>
 
:

whitespace_checker = nodes3.getNodeValue().trim();

but this line of code throws an error:
error: sq_string cannot be indexed with .

strtrim () also doesn't work, as it seems to be incompatible with this
particular object type
https://www.gnu.org/software/octave/doc/v4.0.0/Manipulating-Strings.html#XREFstrtrim

whitespace_checker = strtrim (nodes3)
error: strtrim: S argument must be a string or cellstring

Does anyone know a working solution? Thanks.
