Hello sirs !
I would like to submit a problem I have concerning an output of a DOM object
to a file.
I have made a method which write this object in a tree-view, by adding
recursively new-line characters and spaces, depending on the depth of the
node. That works fine for objects newly created.
If I load an already existing XML file for parsing (file which contains
already a tree-aspect), play with it and try to ?output? it to a file, I get
double new-line characters and spaces. So I?ve implemented a ?boolean? to
indicate if it?s desired a tree-view or not (to make the distinction between
the newly created DOM object and that one taken from a existing file). This
works fine as long as I keep this clear separation.
What if I?m loading a DOM object and try to add some new elements?
If I have: addNewLineCharacter(false)
I?ll get something like:
<oldelement>
sometext
</oldlement><newelement>another text</newelement>
If I have: addNewLineCharacter(true)
I?ll get something like:
<oldelement>
sometext
</oldlement>
<newelement>
another text
</newelement>
So my question is: does an element with one ?child? contains some _TextNode_s
too, for ?\n? characters and spaces? How can I ignore the ?whitespaces??
I have implemented myself the writing method and I can?t understand why if I?m
loading a XML file and having it in memory, I still have those characters used
only for ?pretty-printing?.
I would rather prefer some ?technical explanations? than pointing to some
existing methods.
Sincerely,
silviu leahu
