empty document variables

[Jan Kucera]

Hi, XML Word format, I set these variables:
<w:docVars>
<w:docVar w:name="myVar1" w:val="Kibo" />
<w:docVar w:name="myVar2" w:val="Xibo" />
<w:docVar w:name="myVar3" w:val="Jaffo" /> ;-)))) getting loving
these...
<w:docVar w:name="myVar4" w:val="" />
<w:docVar w:name="myVar5" w:val="" />
</w:docVars>

In the document, I have fields that refers to these variables.
However, the variables with empty strings are not present in the document!
The field reports an error and ActiveDocument.Variables.Count returns 3.

How can I set the variables to empty string?

Thanks,
Jan

You can't. It is a holdover from the days before VBA when the method of
deleting a variable was to set it to a blank string. The nearest you can get
is to set it to a single space, and manage your code so that a single space
is treated as an empty string.

Well, nothing else remains so I will do like that. But why is the Word then
saving variables with empty strings......

Thanks for pointing that out before I get mad , Jan.

A string containing a space is not an empty string... ;-)

I think the question Jan was asking is why, if when you set a Variable to an
empty string and it therefore disappears from the Variables collection in
VBA, does the tag of the Variable still appear with empty content when you
save the file as XML?

And I have no definite answer. I suspect it is a bug.

Yes Jonathan, that was the question - thanks. ;-)
However you wrote a new information to me - when I set the variable to the
empty string, it will be deleted?
I was sooo near using Variables.Add("myVar", '") just to define it and set
later...

Yes. At least, it will disappear from the Variables collection in VBA. As
you have seen, the matching XML tag seems not to disappear.

Well done.
