使用xslt确定目录中的文件_Xslt_Xslt 2.0

使用xslt确定目录中的文件

xslt

使用xslt确定目录中的文件,xslt,xslt-2.0,Xslt,Xslt 2.0,我正在替换许多元数据记录中的分发部分，以包括对其他非xml文件的可选引用。每个xml元数据记录都在一个单独的文件夹中，在每个这样的文件夹中可能有PDF文档，也可能没有Excel文件。这三个文件有独立的名称。我基本上需要一个目录列表，我可以访问和操作它 <xsl:strip-space elements="*" /> <xsl:template match="gmd:distributionInfo" > <gmd:distributionInfo>

下面是我一直在尝试的部分，尽管目前它确实使用Kernow Saxon 9PE编译。第一部分似乎构造了到所需子目录的正确路径，尽管带有“file:/”前缀。
我的问题是：

<xsl:strip-space elements="*" />

<xsl:template match="gmd:distributionInfo" >
    <gmd:distributionInfo>
        <gmd:distributorTransferOptions>
            <!-- construct path to directory containing xml metadata and non-xml files -->
           <xsl:variable name="pathParts" select="tokenize(base-uri(),'/') " />
            <!-- remove filename.extension, reconstruct path -->
            <xsl:variable name="directory" select="string-join((remove($pathParts,count($pathParts))),'/')" />
            <gmd:dir>
                <gco:CharacterString>
                    <xsl:value-of select = "$directory" />
                </gco:CharacterString>
            </gmd:dir>
            <!-- loop thru all files to obtain filenames -->
            <xsl:for-each select="for $filename in collection(concat($directory, select='*.*')) return $filename " >
                <!-- temporary? override to enable xslt compilation -->
                <xsl:variable name="filename" select= "base-uri()" />
                <gmd:name>
                    <gco:CharacterString>

我是否需要继续努力来确定路径？（似乎是“unxsl-ish”）。Kernow很容易在每个子目录中找到metadata.xml文件

我认为我的“for each”语句不正确。在它确实执行的版本中，我临时将“select=”限制为“select=*.xml”（并且它只执行metadata.xml文件）

如果没有提到的覆盖，我会得到“变量文件名尚未声明（或其声明不在范围内）”
