DataSet Schema（xml：space =" preserve"） [英] DataSet Schema (xml:space="preserve")

问题描述

我有一个基于架构的DataSet。



选择元素应包含非空字符串值ex："   ;         "

I have a DataSet that is based on a schema.

Select elements are expected to contain non empty string values ex: "           "

当我拿出值为非空字符串的DataSet xml元素时，属性xml：space =" preserve"添加...这是我读过的正确的功能。



我的问题是如何修改我的模式，以便当xml：space ="保存"是否存在我仍然可以验证模式？

When I pull out the DataSet xml elements where the value is a non empty string the attribute xml:space="preserve" is added... which is correct functionality from what I've read.

My question is how do I modify my schema so that when xml:space="preserve" is present I still can validate against the schema?

在此示例中，myText元素可以包含至少包含一些非空白字符的常规字符串...它也可以包含非空字符串"               "。

In this sample the myText element can contain regular strings with at least some non whitespace characters... it can also contain a non empty string like "               ".

< xs：element
name = " myDataTable "
minOccurs = " 0 " >

    < xs：complexType >        < xs：sequence >

              < xs：element
名称 = " myID "
类型 = " xs：int " />

              < xs：element
名称 = " myText "
类型 = " xs：string " />

         < / xs：sequence >

    < / xs：complexType >

< / xs：element >

<xs:element name="myDataTable" minOccurs ="0">
     <xs:complexType>
          <xs:sequence>
               <xs:element name="myID" type="xs:int"/>
               <xs:element name="myText" type="xs:string"/>
          </xs:sequence>
     </xs:complexType>
</xs:element>

推荐答案

xml：space =" preserve"表示应用程序保留所有空白区域的意图，I不会影响你的验证。

xml:space="preserve" indicates the intent that applications preserve all the white space, I don't it will affect your validation.
