Summary: XML Plugin: Separate/Join XML/HTML Tag Attributes

Initial Comment:
In some XML and HTML code (ColdFusion as well) tags can become very long thanks to many attributes, or just some long attributes.

This feature would split the attributes into their own line and also do the reverse (i.e. join lines that are already split).

Possible options:
* Allow user to choose whether or not to indent the separated lines, or to keep them at same indention level as the first one.
* Placement of the last ">"...
 a) Allow user to choose whether the last ">" gets put on a separate line, or is at the end of the last attribute.
 b) Allow user to indent last ">" flush with attributes or at same level as opening "<".

Benefits:
* Permanent Code Alteration: When you've adopted someone else's web site, who likes to keep tags in long horizontal lines, it's easy to convert that to your method, if you like them separated.  Or vice-versa.
* Temporary Code Viewing: For cases when you want to keep the code one way, but view it temporarily in the other, then convert it back.  For instance, to see all of an XML tag's attributes at once, perhaps make a small edit, then re-join them back into one line.
* This helps to limit horizontal scrolling, the bane of many developers.


Example of "Separate" Feature:

<table cellpadding="4" cellspacing="0" border="0" width="100%" bgcolor="#eeeeee">

would become:

<table 
  cellpadding="4" 
  cellspacing="0" 
  border="0" 
  width="100%" 
  bgcolor="#eeeeee"
>



Example of "Join" Feature:

<table 
  cellpadding="4" 
  cellspacing="0" 
  border="0" 
  width="100%" 
  bgcolor="#eeeeee"
>

would become:

<table cellpadding="4" cellspacing="0" border="0" width="100%" bgcolor="#eeeeee">

Thank you.

I added a few lines to the xmlindenter, it seems to work pretty well. 
Right now I have the code toggling between "split" mode and "join" mode via
a System property.  I checked this in for others to see, revision 9839. 
Use the bean shell (Utilities - BeanShell - Evaluate BeanShell Expresion)
to run System.setProperty("xmlindenter.splitAttributes", "true") to turn on
the "split" mode, unset the property return to "join" mode.  Of course,
there would need to be updates to the option pane for this if everyone
likes this solution.  I didn't do anything about the trailing > yet.

There is already a "split" action, I didn't add a new action yet. I just
made it do something sensible when you are inside a tag. Try using the
split action now. What does it do?

Now all we need is a join, which will be trivial once I figured out how to
get the parsed attributes from one of these many tree structure objects
which are already in memory.

Hi Alan,

I'm wondering if this feature wouldn't be better placed into the
XmlIndenter rather than XML itself?

I was trying to extract the attribute data by getting the current
TreeNode's UserObject. But for some reason, I am unable to get the
attribute data in XML. It appears as null. What's a good way of getting the
attribute data of the current node? I'd rather reuse some of the parsing
that already happened on the XML element, seeing as there is a lot of
parsing code already there.

Dale, any ideas what I am doing wrong here?

File Added: Xml.Split-Tag.patch
