The white space inside the tags, e.g. <a href=""> is not part of the data
and always ignored.
The discussion is only about the space in the data. That means outside the
tags.

Again:
Each format can define it. But it is typical to ignore data that contains
only white space. For instance it is typical that the following has the
same meaning:

<short><var><var/></short>

<short>
  <var>
  </var>
</short>

As soon as the data contains one non white space character every character
counts. The following is not the same:

<var>
a
</var>

<var>a</var>

Note: HTML treats multiple white space as one. But this is not typical for
xml.
