The present invention provides hemicellulytic enzyme variants. Specifically, the present invention provides xylanase variants having one or more modifications as compared to a parent xylanase enzyme resulting in at least one improved property. In addition, the present invention provides compositions comprising a xylanase variant of the invention. The present invention also provides methods of degrading hemicellulotic material, including arabino-xylan using compositions comprising a xylanase variant of the invention. 2. The xylanase variant according to claim 1 , wherein at least 4 out of 20 possible amino acid substitutions at the productive position makes the xylanase variant able to meet at least one of the criteria a) to c) claim 1 , and wherein the productive position is selected from the group consisting of 135 claim 1 , 28 claim 1 , 57 claim 1 , 62 claim 1 , 70 claim 1 , 79 claim 1 , 89 claim 1 , 102 claim 1 , 105 claim 1 , 118 claim 1 , 151 claim 1 , 153 claim 1 , 160 claim 1 , 181 claim 1 , 184 claim 1 , 200 claim 1 , 220 claim 1 , 232 claim 1 , 262 and 298 claim 1 , 4 claim 1 , 21 claim 1 , 25 claim 1 , 30 claim 1 , 56 claim 1 , 59 claim 1 , 64 claim 1 , 65 claim 1 , 71 claim 1 , 74 claim 1 , 77 claim 1 , 98 claim 1 , 99 claim 1 , 100 claim 1 , 103 claim 1 , 104 claim 1 , 106 claim 1 , 113 claim 1 , 115 claim 1 , 117 claim 1 , 120 claim 1 , 134 claim 1 , 141 claim 1 , 142 claim 1 , 148 claim 1 , 150 claim 1 , 152 claim 1 , 156 claim 1 , 161 claim 1 , 163 claim 1 , 167 claim 1 , 176 claim 1 , 180 claim 1 , 193 claim 1 , 198 claim 1 , 199 claim 1 , 201 claim 1 , 202 claim 1 , 215 claim 1 , 217 claim 1 , 227 claim 1 , 229 claim 1 , 230 and 233 claim 1 , and wherein the polypeptide set forth in SEQ ID NO:2 is used for numbering.3. The xylanase variant according to or claim 1 , wherein at least 8 out of 20 possible amino acid substitutions at the productive position makes the xylanase variant able to meet at least one of the criteria a) to c) claim 1 , wherein ...
