我尝试了一个 foreach 循环，其中的键和值位于另一个 foreach 循环中，但我无法将 service 元素与 leg 元素相匹配，因为它们具有独立的循环。
考虑 XSLT, the special-purpose language designed to transform XML files such as handling all the concatenation of values and matching of leg ids. If needed, XSLT can even convert to HTML. PHP can run XSLT 1.0 scripts with its xsl class 使用 DOMDocument 库。
