我有这个示例文档:

<root>
    <span class="a">te</span><span class="a">st</span> <span class="a">tag</span>
    some other text
    <span class="b">keep</span>
</root>

我想有这样的事情:

<root>
    <span class="a">test tag</span>
    some other text
    <span class="b">keep</span>
</root>

或者至少这个:

<root>
    <span class="a">test</span> <span class="a">tag</span>
    some other text
    <span class="b">keep</span>
</root>

class="a"跨度可变计数。 在XSLT中可以吗?

试图解决:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="node() | @*">
        <xsl:copy>
            <xsl:apply-templates select="node() | @*"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="*/span[@class = 'a']"/>
    <xsl:template match="*/span[@class = 'a'][1]">
        <span class="a">
            <xsl:for-each select="../span[@class = 'a'] | ../text()[. = ' ']">
                <xsl:choose>
                    <xsl:when test=". = ' '">
                        <xsl:copy/>
                    </xsl:when>
                    <xsl:otherwise>
                        <xsl:value-of select="./text()"/>
                    </xsl:otherwise>
                </xsl:choose> 
            </xsl:for-each>
        </span>
    </xsl:template>
</xsl:stylesheet>

但是当我有这个输入时?

<root>
    <span class="a">te</span><span class="a">st</span> <span class="a">tag</span>
    some other text
    <span class="b">keep</span>
    <span class="a">te</span><span class="a">st</span> <span class="a">tag</span>
</root>

如何解决这个问题?

第二种变体可以通过以下方式实现:

XSLT 1.0

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

<xsl:key name="grp" 
         match="span[@class='a'][preceding-sibling::node()[1][self::span[@class='a']]]" 
         use="generate-id(preceding-sibling::span[@class='a'][not(preceding-sibling::node()[1][self::span[@class='a']])][1])" />

<!-- identity transform -->
<xsl:template match="@*|node()">
    <xsl:copy>
        <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
</xsl:template>

<xsl:template match="span[@class='a'][not(preceding-sibling::node()[1][self::span[@class='a']])]" priority="1">
    <span class="a">
        <xsl:for-each select=". | key('grp', generate-id())" >
            <xsl:value-of select="."/>
        </xsl:for-each>
    </span>
</xsl:template>

<xsl:template match="span[@class='a']"/>

</xsl:stylesheet>

通过更多工作,您可以在组中包含散布的仅限空格的文本节点。或者,看一下称为“兄弟递归”的技术。
