我正在尝试针对模式验证我的xml,但是当我运行代码时,我收到错误。 xml(sample.xml)是:
<?xml version="1.0" encoding="utf-8"?>

我使用xml文件在线生成了模式,所以我有理由相信那里不应该有任何错误。 我使用的vba代码是:
Sub test()
Dim xDoc As New MSXML2.DOMDocument60
Dim xLists As IXMLDOMElement
Const dir = "C:\"
Dim xSchema As New MSXML2.XMLSchemaCache60
Dim xSchemaErr As IXMLDOMParseError
Call xSchema.Add("urn:schemas-microsoft-com:datatypes", LoadXML(dir & "sample.xsd"))
Set xDoc = LoadXML(dir & "sample.xml")
Set xDoc.Schemas = xSchema
Set xSchemaErr = xDoc.Validate
Set xDoc = Nothing
End Sub
Private Function LoadXML(strFilename As String) As MSXML2.DOMDocument60
Dim xDoc As New MSXML2.DOMDocument60
Dim bLoadSucceeded As Boolean
Dim fso As New FileSystemObject
With xDoc
.async = False
.validateOnParse = False
.resolveExternals = False
End With
If (fso.FileExists(strFilename)) Then
bLoadSucceeded = xDoc.Load(strFilename)
If (bLoadSucceeded) Then
Set LoadXML = xDoc
Else
Call MsgBox("Load XML document failed", vbCritical, "Warning")
Set xDoc = Nothing
Exit Function
End If
Else
Call MsgBox("Unable to find specified XML file to load", vbCritical, "Warning")
Set xDoc = Nothing
Exit Function
End If
Set xDoc = Nothing
End Function
问题出现在这里
Call xSchema.Add("urn:schemas-microsoft-com:datatypes", LoadXML(dir & "sample.xsd"))
错误The parameter is incorrect
,但我看不出哪个参数导致了问题。查看XMLSchemaCache60
的add方法的文档,我看不出有任何关于此错误的提及。
有谁知道这可能是什么?
由于
编辑:
好吧,在过去几天仔细考虑之后,我仍然不确定我是否完全理解来自Michael Kay
的评论,而不是那些暗示xsd几乎没用的评论,因为我和xmlgrid一样无用.net,我试了另一个;这次https://devutilsonline.com/xsd-xml/generate-xsd-from-xml这就是我得到的:

看起来它已经解决了导入架构问题?????但是我现在得到一个新的错误:
sample.xsd#/schema/complexType[17][@name = 'DESC2Type']/simpleContent[1]/extension[1]/attribute[1]
Undeclared XSD attribute : '{urn:schemas-microsoft-com:datatypes}dt'.
我无法理解为什么这是一个未声明的属性 - 对我来说,这看起来就像同一个文档中的其余部分,虽然名称不同!!
答案 0 :(得分:0)
架构确实无效(这意味着您选择的在线工具是错误的 - 事实上,这是废话)。
首先,
<xs:attribute name="dt:dt" type="xs:string">
非常不正确:name
属性必须是简单的NCName(无冒号名称)。如果属性与包含元素位于不同的名称空间中,则模式需要包含该名称空间的单独模式文档的xs:import;该属性需要在导入的模式文档中声明,并使用ref
属性在主模式文档中引用:
<xs:attribute ref="dt:dt"/>
其次,元素声明不能同时具有type
属性和complexType
子元素。描述具有属性且具有文本内容的元素的正确方法是使用“具有简单内容的复杂类型”,如下所述:
XML Schema: Element with attributes containing only text?
我不得不说你得到的错误信息也很糟糕。 Saxon为您提供了以下形式的消息列表:
Error at xs:attribute on line 13 column 81 of test.xsd:
No namespace prefix is allowed in this name {dt:dt}
后面是表格的消息列表:
Error at xs:element on line 16 column 66 of test.xsd:
A <complexType> element must not appear as a child of an <xs:element> with a @type attribute
答案 1 :(得分:0)
如果您正确地错误处理了捕获运行时异常的方法,尤其是使用MSXML之类的API,则会收到更相关的错误消息,显示架构问题。
