I am fairly certain the “ {} “ before the \else introduces spaces.

The extra space is because you have a space between {first_name} and
{\xmlatt... on line 9 of xml.tex.

Greetings,
I'm typesetting an address book whose addresses are in XML. A typical
entry has this structure:
email="" mobile="" />
initials and birthday are required, first_name can be left blank and
email, mobile and maiden_name are optional.
I've written a macro (name) to compose the name, i.e. initials,
first_name (maiden_name), and another macro (nameemaillink) to make the
name a link associated with an email address.
% Derive an individual's name
\def\name#1%
{\ifxmlattempty{#1}{first_name} {\xmlatt{#1}{initials}} \else
{\xmlatt{#1}{initials}, \xmlatt{#1}{first_name}} \fi
\ifxmlattempty{#1}{maiden_name} {} \else {
\tfxx(\xmlatt{#1}{maiden_name})} \fi}
You have a few spaces in the definition of your command (e.g. the space
after \else and another one after the following { in the main_name
attribute) which end as multiple spaces in the output.
While you can fix the problem by removing the spaces a better solution
is to use the texdefinition environment to create your command, you can
even use blank lines to structure the arguments.
To avoid problems with existing commands it is good practice to use
camelcase for your own commands.
begin example
\starttexdefinition Name #1
\ifxmlattempty{#1}{first_name}
\xmlatt{#1}{initials}
\else
\xmlatt{#1}{initials}, \xmlatt{#1}{first_name}
\fi
\ifxmlattempty{#1}{maiden_name}
%
\else
{\tfxx(\xmlatt{#1}{maiden_name})}
\fi
\stoptexdefinition
end example
