I write from Spain I have one doubt, and I wonder if you can help me. I want my xml file to have required "attlist", so I put in my DTD file the next text: ..... <!ATTLIST Identificacion IdCliente NMTOKEN #REQUIRED Nombre NMTOKENS #REQUIRED Apellido1 NMTOKENS #REQUIRED Apellido2 CDATA #IMPLIED> .... The problem is: 1. If in the corresponding xml file the IdCliente attribute equals "", it does not produce error !! 2. If in the corresponding xml file the Nombre attribute equals "JohnO" it's OK, but if it is equals "John'O" (nfpl !!!), it gifs error!!! How can I do to get that in the first case produce error and in the second not to produce error. Thanks and excuse my poor English begin 600 malgonzalez.vcf M8F5G:6XZ=F-A<F0@#0IN.DQO<&5Z.TUI9W5E;"!!;F=E;`T*>"UM;WII;&QA M+6AT;6PZ1D%,4T4-"G5R;#IW=W<N:6YD<F$N97,-"F]R9SI!5$Q!3E1%(%-) M4U1%34%3+"!3+DPN.TEN9V5N:65R:6$@>2!$97-A<G)O;&QO#0IV97)S:6]N M.C(N,0T*96UA:6P[:6YT97)N970Z;6%L9V]N>F%L97I`:6YD<F$N97,-"F%D M<CMQ=6]T960M<')I;G1A8FQE.CL[8R\@5F5L87IQ=65Z(#$S,CTP1#TP03M- M861R:60@("`Y,2`S-#@@,3(@-S@[.SM%<W!A\6$-"F9N.DUI9W5E;"!!;F=E 4;"!,;W!E>@T*96YD.G9C87)D#0H= ` end
