How about:

<robot>
<description>ar mar3</description>
:
:
</robot>

XML editor + xpath makes this way more easier to use by humans compared to
normal comments. Also, if you declare several of comment elements
(summary, description, author, etc.) you can auto generate documentation
etc.

Re: how to print newline in xml?

Thank you for a possible solution, but it's not what I'm looking for,
cause something like  would look quite similar... for
big elements like robot it would be ok to use comment as a child of
element - but imagine I'd like to comment transformation:

<transformati on x="0" y="0" z="0"/> I wouldn't like to make this
element parent of a description - it is not nice - I have lots of such
elements.

It is important that a user after having a glance at the document is
able to quickly find and change some values. I don't want to bother him
with reading documentation nodes - but if he needs - they should be
there... the only possible solution I can think of would be:

<Robot>
<verbose mode="enabled"/> 
<CollisionCheck er type="vcollide"/> 
<Visualisatio n mode="3DModel"/> 



<RootJoint> 
<Name value="Armar3"/> 
<DH> 
<alpha value="0"/>
</DH>

<ID value="0"/> 
<ChildNodes childID="1"/> 
</RootJoint>

<ChildJoint>
<Name value="Platform "/>
<JointTransform ation>
<RotationAxis X="0" Y="0" Z="1" INIT="0"/>
<TranslationFro mParent X="0" Y="0" Z="0"/>
</JointTransforma tion>
<Visualisatio n> 
<IVModel file="model/platform.iv"/> 
</Visualisation>
<ID value="1"/> 
<ChildNodes childID="2"/> 
</ChildJoint>

Then add the comment to the parent of transformation, or an other option
might be:

<transformati on x="0" y="0" z="0" description="so me description"/>

Several of your comments are stating the obvious, it's like:

x++ increments the value x contains with one

Picking a better name would solve that problem. DenavitHartenbe rg might be
a bit long though.

BTW: don't top post.

Re: how to print newline in xml?

Thank you! I think description as an attribute is readable. But now I'm
thinking about the order of attributes cause I noticed that for
instance X="0" Y="0" Z="0" set in this order by my script is printed
like X="0" Z="0" Y="0" therefore it could be messy - I wouldn't like
the description to be somewhere between the other attributes. But I
have to test it.

I'll have to consider some better names for the elements

Sending my regards, Anatoli

I don't know the library you are using, and also have way more experience
in Perl. I guess that the attributes are stored in a dictionary, which has
no order, and hence the original order of the attributes is lost. In Perl
with some modules I use I can chose to use a list or a hash (=
dictionary). With the former the original order is preserved.

I am sure something like that is possible in Python as well.

Re: how to print newline in xml?

I use Python/XML packages are xml.dom.minidom and xml.dom.ext (second
just for PrettyPrint)

You don't need xml.dom.ext for prettyprint. You can use
doc.toprettyxml ()

I gather you want to tweak the prettyprinter to not add the newline
before the comment. The only way to do this is to write your own
printing logic, which is really not that hard, if you just start by
copying the code from .writexml (used by .toprettyxml).

But there's an even easier (if slower) way: pretty print the document,
then parse it in again, remove the text node between the element in
question and the following comment, and then use .writexml() to
serialize it it again.

A few general notes:

* You cannot set the order of attributes in most XML tools, whether
Python or not. This is unfortunate for people who would like to
preserve such details for usability reasons, but that's just the way
XML is. The closest you can get is by using canonicalizatio n [1],
which is available in PyXML as xml.dom.ext.c14 n. It just so happens
that canonical XML leaves the attributes in the order you want. You
won't always be so lucky.

* You can always create text nodes by using doc.createTextN ode.

* You can always remove text nodes (or any other kind) by using
..removeChild

* It's much easier to navigate if you use XPath. PyXML has an
xml.xpath module you can use.

Good luck.
