I have 2 xml documents <a> <lookuptag1>data</lookuptag1> <lookuptag2>field1</lookuptag2> </a> <b> <data> <field1>111</field1) <field2>222</field2) </data> </b> I can read and parse each ok, ie: $xml_a->lookuptag1, $xml_b->data->field1 however, If I construct the reference to b field1, (using the fields from a) I cannot evaluate or reference it. even just building the reference from inline text is not working. for example: $b = "\$xml_b->data->' . 'field1'; echo "$b"; echo eval($b); eval ( "\$f1 = \"$b\";"); echo $$b; nothing seems to work. Any ideas what I need to do. thanks, jon
