xml 相关问题

Public Function CountElementDescendents(ByVal CFGFile As String,_ 'Path to Config.xml ByVal Parent As String,_ 'Name of element to search descendents eg. 'package' ByVal ParentIndex As String,_ 'Index value of element to search descendents eg. '1' ByVal ElementCount As String_ 'Name of descendent elements to count 'eg. 'driver' ) As Integer 'Return number of matching elements eg. '2' Dim ReturnValue As Integer = 0 Dim Xe As XElement Xe = XElement.Load(CFGFile) Dim Query As IEnumerable(Of XElement) = Xe.Elements(Parent).Attribute("index="&ParentIndex).Descendants(ElementCount) ReturnValue = Query.Count() CountElementDescendents = ReturnValue End Function 我不确定这是否可行，或者即使我已经采取了构建 XML 的最佳方法，有人可以提供一些帮助或建议吗？谢谢！感谢@dbasnett 和@Craig 的帮助，你们太棒了！我会将其标记为已回答。尝试一下。 LINQ 查询检查所有驱动程序元素并选择其父级是索引为 1 的包的元素。 'for testing use XML literal Dim xe As XElement xe = <dataset> <packages> <package index="1"> <desc>First Package</desc> <rmabool>1</rmabool> <rmaref>RMACASE1</rmaref> <bootfiles>1</bootfiles> <image>1</image> <driver>3</driver> <driver>4</driver> </package> <package index="2"> <desc>Second Package</desc> <bootfiles>2</bootfiles> <image>2</image> <driver>3</driver> </package> <package index="3"> <desc>Third Package</desc> <bootfiles>3</bootfiles> <image>2</image> <driver>3</driver> </package> </packages> </dataset> ' I would like to count how many elements, named 'driver', ' are contained in an element named 'package' with an index matching "1". ' Dim ie As IEnumerable(Of XElement) ie = From el In xe...<driver> Where el.Parent.Name.LocalName = "package" AndAlso el.Parent.@index = "1" Select el 编辑：作为函数 Private Function Srch(ElementToSearch As XElement, ParentName As String, ParentIndex As String) As IEnumerable(Of XElement) Dim ie As IEnumerable(Of XElement) ie = From el In ElementToSearch...<driver> Where el.Parent.Name.LocalName = ParentName AndAlso el.Parent.@index = ParentIndex Select el Return ie End Function 编辑2 - 更新功能 Private Function Srch(ElementToSearch As XElement, FindThis As String, ParentName As String, ParentIndex As String) As IEnumerable(Of XElement) Dim ie As IEnumerable(Of XElement) ie = From el In ElementToSearch.Descendants(FindThis) Where el.Parent.Name.LocalName = ParentName AndAlso el.Parent.@index = ParentIndex Select el Return ie End Function 测试 Dim rslts As IEnumerable(Of XElement) rslts = Srch(xe, "bootfiles", "package", "1")

Java无法解析符号xsd文件

我有以下 .xsd 文件：我有以下 .xsd 文件： <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://soapexercise.plonca.sri.pja.edu/employees"
