我收到一条错误，指出''不是'整数'的有效值。我尝试使用 nillable =“true”作为元素并尝试更改使用限制的模式值。 xml文件中的 parentInstanceId 元素没有任何值。但是我应该给它一个20个字符的限制。
这是我的xsd文件。

答案 0 :(得分：2)
在XML文档中，您需要<parentInstanceId xsi:nil="true"/>表示没有值，请参阅https://www.w3.org/TR/xmlschema-0/#Nils以获取完整示例。
答案 1 :(得分：2)
有两种方法可以定义一个接受整数或零接口的simpleType（零长度字符串）：
（a）定义一个具有两个成员类型的联合类型，一个是xs：integer（或其子类型），另一个是xs：string的限制，长度为＆＃34; 0＆＃34;。
（b）定义一个列表类型，项目类型为xs：integer，maxLength =＆＃34; 1＆＃34;。
就验证XML而言，这两种方法是等效的，但它们可能与数据绑定技术或模式感知XSLT和XQuery的行为不同。
