关于属性名称的问题

Question

Xml 文档

我对来自 sharepoint 的 xml 属性名称有疑问，其中包含 xmldoc 中的 description0、ows_x0020_long_desc 等属性名称

请您告诉解决方法。

Answer 1

在 xml 中返回数据时，SharePoint 将始终使用这个 fromat。

• 字段名称将由 ows_ 前缀
• 将使用字段的内部名称而不是显示名称。

• SharePoint 中的内部字段名称包含特殊字符的 unicode 等效项
  例如如果您从 SharePoint UI 创建一个名为“字段名称”的字段， SharePoint 将创建内部名称为“Field_x0020_Name” 其中 0020 是空间的 unicode 表示。

  如果字段是由代码或功能创建的，但是您可以指定自己的内部名称和显示名称。

因此，如果您要解析此类 xml，则必须编写代码以记住这些规则。

SharePoint 不会在字段的内部名称中添加 x0020 转义序列，除非在从 UI 创建字段时显示名称中有空格。 同样，一旦创建了字段，更改显示名称对字段的内部名称没有影响。 因此，如果您从 UI 创建一个字段“Long Desc”，然后将名称更改为“LongDesc”，则内部名称仍将是 Long_x0020_Desc。
