22.4.2 元素¶
以下元素定义了该命名空间的内容:
Elements
The following elements define the contents of this namespace:
22.4.2.1 array (数组)¶
数组元素定义数组变体类型。 数组内容应具有由 baseType 属性指定的统一类型。 数组的内容是使用适当变体类型的重复子元素来定义的。
可以通过使用“,”分隔符在 lBound 和 uBound 属性中指定每个维度的长度来定义多维数组。 多维数组的子元素按照声明维度的顺序沿每个维度进行索引。
换句话说,数组应填充如下:
- 第一个索引应增加到其最大值 [Example: [0,0,0] 至 [max,0,0] end example]
- 第二个索引应增加到其最大值 [Example: [0,1,0] 至 [0,max,0] endexample]
- 应填充后续索引,直到添加所有提供的值
- 数组中的所有其他值均应为空值 (i.e. 不应假定默认值).
Example
“i4”类型的 2x3 变体类型数组指定如下:
<vt:array lBounds="0,0" uBounds="1,2" baseType="i4">
<vt:i4>0</vt:i4>
<vt:i4>1</vt:i4>
<vt:i4>2</vt:i4>
<vt:i4>3</vt:i4>
<vt:i4>4</vt:i4>
</vt:array>
得到数组: [0,0] = 0, [1,0] = 1, [0,1] = 2, [1,1] = 3, [0,2] = 4.
属性 | 描述 |
---|---|
baseType (数组基本类型) |

[Note: 该元素内容模型 (CT_Array) 的 W3C XML 模式定义位于 [§A.6.4] 中。 end note]
array (Array)
The array element defines the array variant type. Array contents shall be of uniform type as specified by the baseType attribute. The contents of an array are defined using repeated child elements of the appropriate variant type.
Multi-dimensional arrays can be defined by specifying the length of each dimension in the lBound and uBound attributes through the use of the "," delimiter. Child elements of multi-dimensional arrays are indexed along each dimension in the order the dimensions are declared.
In other words, the array shall be filled as follows:
- The first index shall be incremented to its maximum value [Example: [0,0,0] to [max,0,0] end example]
- The second index shall be incremented to its maximum value [Example: [0,1,0] to [0,max,0] endexample]
- Subsequent indices shall be filled until all provided values have been added
- All other values shall have null values within the array (i.e. no default value shall be assumed).
Example
A 2x3 variant type array of type "i4" is specified as follows:
<vt:array lBounds="0,0" uBounds="1,2" baseType="i4">
<vt:i4>0</vt:i4>
<vt:i4>1</vt:i4>
<vt:i4>2</vt:i4>
<vt:i4>3</vt:i4>
<vt:i4>4</vt:i4>
</vt:array>
