php - 根据值添加和定位 XML 节点以生成 XML 文档

Question

我正在开发一个应用程序，它将采用 2 个 XML 文件并合并为 1 个。目前我可以生成一个 XML 文件，但它的格式不是我想要的，而且我现在已经碰壁了。

应用程序读取 2 个 XML 文件，然后从其中一个 XML 文件中检查每个员工记录。
对于第一个 XML 文件中的每个员工记录
1. 它在第二个 XML 中查找相应的记录
2. 一旦被发现，它会生成一系列新节点并使用第二个 XML 文件中的信息填充它

我想将这些新节点放置在特定点的相关人员记录中（目前它只是将它们全部转储到 XML 文档的底部）

我遇到的问题是从第二个 xml 中获取相应的数据，以便与第一个 xml 文件中的数据一起放置。如您所见，它只是放在文档的底部，并没有链接到相关记录（生成的输出），数据应该出现在上面，我目前不知道如何做到这一点，任何建议都将不胜感激。谢谢

您正在创建一个新的容器元素ContractOrServiceGroup，然后将其附加到文档的根元素，然后在其上附加更多元素。

            $newItem = $schoolExtract->documentElement->appendChild(
                    $schoolExtract->createElement('ContractOrServiceGroup')
                );

相反，您应该做的是创建新元素及其所有子元素，然后将其附加到文档的适当位置。

例如：

           $newItem = $schoolExtract->createElement('ContractOrServiceGroup');

           foreach (array('ContractType', 'etc')) {
               // build $newItem tree
           }

           // $row2 I think is the StaffDetails element in schoolExtract.xml?

           // If so, this will add to the end of StaffDetails's parent:
           $row2->parentNode->appendChild($newItem);

           // This will add to the beginning:
           $row2->parentNode->insertBefore($newItem, $row2->parentNode->firstChild);

           // This will add it before StaffDetails:
           $row2->parentNode->insertBefore($newItem, $row2);

           // This will add it after:
           $row2->parentNode->insertBefore($newItem, $row2->nextSibling);

这段代码很难理解。您是否考虑过改用SimpleXML？对于您正在使用的数据 XML，它是一个更清晰的 API。

PHP的

schoolExtract.xml

kcsFinalExtract.xml
