question on validating links from databases

When using the W3C MarkUp Validation Service I receive errors on my files 
because of the URIs from database pages. Since using a database is quite 
prevalent, could the validator be written to ignore the href="....." 
string? The file, except for URIs is compliant, so the "This page is not 
Valid HTML 4.01 Transitional!" is not correct.

Example from my file:
49: <a 
href="http://telecom.unl.edu/equipment/equipment_director.asp?cind=1&grp=Telephone" 
class="leftnav">Telephone

Below are the results of attempting to parse this document with an SGML 
parser. 
Line 49, column 74: cannot generate system identifier for general entity 
"grp" 
...ipment/equipment_director.asp?cind=1&grp=Telephone" 
class="leftnav">Telephone
                                          ^

Line 49, column 74: general entity "grp" not defined and no default entity 
(explain...). 
...ipment/equipment_director.asp?cind=1&grp=Telephone" 
class="leftnav">Telephone
                                          ^

Line 49, column 77: reference to entity "grp" for which no system 
identifier could be generated 
...ipment/equipment_director.asp?cind=1&grp=Telephone" 
class="leftnav">Telephone
                                             ^

Line 49, column 73: entity was defined here 
...uipment/equipment_director.asp?cind=1&grp=Telephone" 
class="leftnav">Teleph..

Thank you for considering this.
