我写了一个XML并试图针对XSD验证它，但是我遇到了一些错误，我无法解决它们。
以下是错误消息：
Error - Line 38, 128: org.xml.sax.SAXParseException; lineNumber: 38; columnNumber: 128; s4s-elt-invalid-content.1: The content of '#AnonType_symptomsmedicindatapatientpatientshospital' is invalid. Element 'element' is invalid, misplaced, or occurs too often.

我理解元素＆＃39;元素＆＃39;在特定的行。我现在检查了我的XSD超过一个小时，但我看不出它的错误。
我希望你能帮助我。

答案 0 :(得分：2)
它抱怨你的架构。
您有xs:element作为多个地方xs:complexType元素的直接子元素，这是不允许的。
您需要将这些元素嵌套在合成器中，例如xs:sequence，xs:choice或xs:all。
例如，要更正症状问题，您可以使用xs:choice：
<xs:element name="symptoms">
<xs:complexType>
<xs:choice>
<xs:element name="symptom" type="xs:string" minOccurs="1" maxOccurs="unbounded" />
</xs:choice>
</xs:complexType>
</xs:element>
