Question

在修改一份文件时,我需要研究地图中的某些节点内容,并撰写这些价值观。

我在转变中勾画了我的地图。

<xsl:variable name="inlinedmap">
    <kat id="stuff">value</kat>
    <!-- ... -->
</xsl:variable>
<xsl:variable name="map" select="document(  )/xsl:stylesheet/xsl:variable[@name= inlinedmap ]" />
<xsl:template match="/">
    <xsl:for-each select="/*/foo">
        <!--  bar  contents should equal to contents of  kat  -->
        <xsl:variable name="g" select="$map/key[.=bar]"/>
        <xsl:choose>
            <xsl:when test="$g !=   ">
                <xsl:value-of select="$g/@id"/>
            </xsl:when>
            <xsl:otherwise>
                ERROR
            </xsl:otherwise>
        </xsl:choose>
    </xsl:for-each>
</xsl:template>

I m always getting ERROR value. I can t put map value s into attributes, because they contain letters that get escaped.

我怎么能做到这一点?

我认为这里有几个问题:

You seem to be looking for key elements in your variable, but they re called kat there (typo?)
You seem to be trying to reference the bar child of the context node inside the loop, but you need to use current() to do that
You should create this map as elements in your own namespace instead of an xsl:variable

这里有一个完整的例子。这一风格:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:my="my">
    <my:vars>
        <kat id="stuff">value</kat>
        <!-- ... -->
    </my:vars>
    <xsl:variable name="map" select="document(  )/*/my:vars/*"/>
    <xsl:template match="/">
        <xsl:for-each select="/*/foo">
            <!--  bar  contents should equal to contents of  kat  -->
            <xsl:variable name="g" select="$map[.=current()/bar]"/>
            <xsl:choose>
                <xsl:when test="$g !=   ">
                    <xsl:value-of select="$g/@id"/>
                </xsl:when>
                <xsl:otherwise>
                    ERROR
                </xsl:otherwise>
            </xsl:choose>
        </xsl:for-each>
    </xsl:template>
</xsl:stylesheet>

用于这一投入:

<root>
    <foo><bar>value</bar></foo>
    <foo><bar>value1</bar></foo>
    <foo><bar>value2</bar></foo>
    <foo><bar>value3</bar></foo>
</root>

a. 产生这一产出(一比):

stuff
ERROR
ERROR
ERROR
