我在节点中有一个字符串,我想将字符串拆分为'？' 并返回数组中的最后一项.

例如,在下面的块中:

<a>
    <xsl:attribute name="href">
        /newpage.aspx?<xsl:value-of select="someNode"/>
    </xsl:attribute>
    Link text
</a>

我想分割someNode价值.

编辑:这是我用来为我的Asp.Net页面加载Xsl的VB.Net:

Dim xslDocPath As String = HttpContext.Current.Server.MapPath("~/App_Data/someXslt.xsl")
Dim myXsltSettings As New XsltSettings()
Dim myXMLResolver As New XmlUrlResolver()

myXsltSettings.EnableScript = True
myXsltSettings.EnableDocumentFunction = True

myXslDoc = New XslCompiledTransform(False)
myXslDoc.Load(xslDocPath, myXsltSettings, myXMLResolver)

Dim myStringBuilder As New StringBuilder()
Dim myXmlWriter As XmlWriter = Nothing

Dim myXmlWriterSettings As New XmlWriterSettings()
myXmlWriterSettings.ConformanceLevel = ConformanceLevel.Auto
myXmlWriterSettings.Indent = True
myXmlWriterSettings.OmitXmlDeclaration = True

myXmlWriter = XmlWriter.Create(myStringBuilder, myXmlWriterSettings)

myXslDoc.Transform(xmlDoc, argumentList, myXmlWriter)

Return myStringBuilder.ToString()

解析包含Java中的命名空间的xpath似乎需要使用NamespaceContext对象,将前缀映射到命名空间URL,反之亦然.但是,NamespaceContext除了自己实现它之外,我找不到任何其他机制.这似乎违反直觉.

问题:是否有任何简单的方法NamespaceContext从文档中获取,或者创建一个或者失败,完全放弃前缀并指定具有完全限定名称的xpath？
