[QUOTE="amilewski, post: 143930, member: 29177"] Nice to see you here James, before I started this thread I had been reading other posts and found your suggestions very usefull. Unfortunatelly, work with this site led me into so many troubles that I' ve decided to abandon this work and start another one with tv.panoramainternetu.pl which seems to provide much more information and channels. And here I've got another problem to solve which seems to be very common - optional fields. Let's concider following example of source html: <tr><td>str1<a>str2</a>str3</td></tr> we parse it to three variables (#v1,#v2,#v3), if all three strings are present in source line variables get correct values, but if line does not contain string2 #v2 gets value of str3 and #v3 becomes empty, in this example #v2 should be empty and #v3 should be of str3. Does anybody have clue how to achive that? [/QUOTE]
