下面是我的输入xml，我想基于supp-part-number生成输出。当前如果supp-part-num是重复的，那么它不会生成单独的块。我在下面提到的是当前输出和预期的输出格式。
输入xml：
<array-list total="4">
<catalog-publish-vO rec-no="1">
<short-desc>NLCTVBL Cable Clips - Round Cable 5-7mm Black</short-desc>
<err-msg>2</err-msg>
<supp-part-num>1101</supp-part-num>
</catalog-publish-vO>
<catalog-publish-vO rec-no="0">
<short-desc>NLCTVBL Cable Clips - Round Cable 5-7mm Black - 1050151244 (100 Pack)</short-desc>
<err-msg>2</err-msg>
<supp-part-num>1101</supp-part-num>
</catalog-publish-vO>
<catalog-publish-vO rec-no="1">
<short-desc>NLCTVBL Cable Clips - Round Cable 5-7mm Black</short-desc>
<err-msg>2</err-msg>
<supp-part-num>1101</supp-part-num>
</catalog-publish-vO>
<catalog-publish-vO rec-no="0">
<short-desc>NLCTVBL Cable Clips - Round Cable 5-7mm Black - 1050151244 (100 Pack)</short-desc>
<err-msg>2</err-msg>
<supp-part-num>1101</supp-part-num>
</catalog-publish-vO>
</array-list>
当前输出：
<array-list exceeds="" total="4">
<catalog-publish-vO>
<part>part_1101</part>
<pendingItem>
