嗨,首先我正在学习复杂的 XSLT 迭代,现在写我遇到了一个查询,其中我在标签信息下有相同的信息,唯一不同的标签是具有不同属性值的 BookingClassAvail,我想组合成一个保留信息标签作为单独的。

如果您在上面看到标签 BookingClassAvail 具有 ResBookDesigCode 和 ResBookDesigQuantity 的不同信息,因此需要逐行堆叠。
<BookingClassAvail ResBookDesigCode="T" ResBookDesigQuantity="180" />
<BookingClassAvail ResBookDesigCode="B" ResBookDesigQuantity="80" />
此外,如果其中的任何信息不同于它应该作为单独的航段出现。
还要注意,上面的一个标签为出港航班,其他信息为进港航班,需要单独保存,只需合并即可。
提前一百万谢谢。
肖恩,我使用了您建议的解决方案,但我遇到了一个错误,因为“无法从已加载的输入文档中删除空格。将输入文档提供为 XmlReader。”
