将 document() 参数传递给 XProc 管道中的 xslt [英] Passing document() parameter to an xslt in XProc pipeline

问题描述

我已经建立了一个 XProc 管道，其中我有一个 步骤.在这个样式表的参数中，我有一个参数，它是一个 document() 节点:

I've set up an XProc pipeline wherein I have a <p:xslt> step. Amoung the parameters of this stylesheet, I have an parameter which is a document() node:

这是 km_to_dita.xsl 样式表:

This is the km_to_dita.xsl stylesheet:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:dctm="http://www.documentum.com" xmlns:ale="http://www.amplexor.com/alcatel"
    exclude-result-prefixes="xs dctm ale" version="2.0">

    <xsl:param name="conf-base" select="'file:/D:/Temp/ALE_config/'" />

    <xsl:param name="output-base" select="''"/>

    <xsl:param name="lang" select="/element()[1]/@language"/>

    <xsl:param name="graphics-reference-names" as="document-node()*" />

    <!-- my templates stuff... -->
</xsl:stylesheet>

因此，我通过以下步骤在我的管道中调用此 XSLT(出于演示目的，它设置了 <p:inline> 但它旨在绑定到一步):

Thus I am calling this XSLT in my pipeline with the following step (for demonstration purpose it is set with a <p:inline> but it is aimed to be bound to the result port of a step):

<p:xslt name="km-dm-to-dita">
    <p:input port="source">
        <p:pipe port="list-dm" step="list-csv"/>
    </p:input>
    <p:input port="stylesheet">
        <p:document href="km_to_dita.xsl"/>
    </p:input>
    <p:with-param name="output-base" select="$dita.data-dir"/>
    <p:with-param name="conf-base" select="$config-dir"/>
    <!--<p:with-param name="graphics-reference-names">
        <p:pipe port="result" step="get-figure-references"/>
    </p:with-param>-->
    <p:with-param name="graphics-reference-names">
        <p:inline>
            <graphic-ids>
                <reference type="symbol" document="dm09011b0281121ef3.xml#G4" filename="g09011b0281d9c449.gif"/>
                <reference type="symbol" document="dm09011b0281121ef3.xml#G3" filename="g09011b0281d9c449.gif"/>
                <reference type="figure" document="dm09011b0281121ef3.xml#F33" filename="g09011b0281d9c44d.gif"/>
                <reference type="symbol" document="dm09011b0281121ef3.xml#G5" filename="g09011b0281d9c451.gif"/>
                <reference type="figure" document="dm09011b0281121ef5.xml#F116" filename="g09011b0281d9c458.gif"/>
            </graphic-ids>
        </p:inline>
    </p:with-param>

    <p:with-option name="output-base-uri" select="$dita.data-dir"/>
</p:xslt>

但是在使用 XML Calabash(在 oXygenXML 中)运行它时失败了，引发的错误是(对不起，伙计们，这是我拥有的所有信息)但是已经确定它是 <p:with-param name=导致此错误的graphics-reference-names">:

But it fails when running it with XML Calabash (in oXygenXML), the error being raised is (sorry folks it's all the information I have) however have determined that it's the <p:with-param name="graphics-reference-names"> that causes this error):

空

有什么想法吗?

推荐答案

如果你使用

<p:input port="source">
    <p:pipe port="list-dm" step="list-csv"/>
    <p:pipe port="result" step="your-other-step"/>
</p:input>

在 XProc 1 中使用 p:xslt version="2.0" 然后

in XProc 1 with p:xslt version="2.0" and then

<xsl:param name="graphics-reference-names" as="document-node()*" select="subsequence(collection(), 2)" />

在 XSLT 代码中，我认为应该可以将另一个步骤的结果用作辅助输入文档(作为默认集合的一部分访问).

in the XSLT code I think it should work to have the result of another step available as a secondary input document (accessed as part of the default collection).
