[URGENT:HELP!!]Entity Reference in DOM and SAX

[st3lla]

Hi All,

How to handle external entity in DOM and how to display internal entity reference in DOM? For example :

i defined this at the bottom of an xml document :

<!ENTITY message "Thank you for your purchases!">
<!ENTITY terms SYSTEM "terms.xml">

Then call it within the document also :

 &terms; 

  &message; 

with terms.xml :
<?xml version="1.0"?>
<terms>
<term>Visa, Mastercard, American Express accepted. Checks will be accepted
for orders totalling more than USD 5000.00</term>
<term>All payments must be made in US currency</term>
<term>Returns within 15 days</term>
<term>International orders may be subject to additional customs duties and
levies</term>
</terms>

Do i have to make parser inside parser for handling external entity in DOM?

I plan to view the content of each entity.But,I confused how to do that.

Could someone help me please???😕

Thank you so much

Regards,
Stella
