You can use an entity. For example, declare the entity in your DTD:
<!ENTITY myaddress "123 Main St">
and reference the entity in the body of your document:
<merchant>
<address>&myaddress;</address>
...
</merchant>
When the document is parsed, the parser replaces the entity with its value
and what your application sees is:
<merchant>
<address>123 Main St</address>
...
</merchant>
The above shows an internal entity, which means that the entity value is
stored in the document. The entity could also be external, meaning it is
stored in any sort of an external resource. The simplest case is when it is
stored in an external file, so your declaration might look like:
<!ENTITY myaddress SYSTEM "addressfile.txt">
However, the system id doesn't need to point to a file -- it could also
point to something like a CGI program to retrieve the entity from a
database.
