XSLT 有 Split() 函数吗? [英] Does XSLT have a Split() function?

问题描述

我在一个节点中有一个字符串，我想在 '?' 上拆分该字符串并返回数组中的最后一项.

I have a string in a node and I'd like to split the string on '?' and return the last item in the array.

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>

我想拆分 someNode 值.

这是我用来为我的 Asp.Net 页面加载 Xsl 的 VB.Net:

Here's the VB.Net that I use to load the Xsl for my Asp.Net page:

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()

更新:这里是在特定节点上拆分 XML 的示例

推荐答案

使用递归方法:

<xsl:template name="output-tokens">
    <xsl:param name="list" /> 
    <xsl:variable name="newlist" select="concat(normalize-space($list), ' ')" /> 
    <xsl:variable name="first" select="substring-before($newlist, ' ')" /> 
    <xsl:variable name="remaining" select="substring-after($newlist, ' ')" /> 
    <id>
        <xsl:value-of select="$first" /> 
    </id>
    <xsl:if test="$remaining">
        <xsl:call-template name="output-tokens">
            <xsl:with-param name="list" select="$remaining" /> 
        </xsl:call-template>
    </xsl:if>
</xsl:template>
