这是xml:

<?xml version="1.0" encoding="UTF-8"?>
    <file>
        <text>
            <p>
               <sentence>I bought kiwi at the grocery store.</sentence>
               <sentence>I also bought bananas at the store.</sentence>
               <sentence>Then, I bought a basket at another store.</sentence>
            </p>
            <p>
                <sentence>You bought kiwi at the grocery store.</sentence>
                <sentence>You also bought bananas at the store.</sentence>
                <sentence>Then, You bought a basket at another store.</sentence>
            </p>
        </text>
    </file>

这是XSLT:

<xsl:stylesheet version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="sentence">
        <p>
            <xsl:apply-templates/>
        </p>
    </xsl:template>
        <xsl:template match="/">
        <html>
            <body>
                <xsl:apply-templates select="file/text/p/sentence[contains(.,$search)]"/>
            </body>
        </html>
    </xsl:template>
</xsl:stylesheet>

我需要在$search时突出显示结果中的$search="kiwi"字词:

我在杂货店买了<mark>奇异果</mark>

你在杂货店买了<mark>奇异果</mark>

请帮忙!

要突出显示搜索字符串的所有匹配项,请更改此项:

<xsl:template match="sentence">
    <p>
        <xsl:apply-templates/>
    </p>
</xsl:template>

为:

<xsl:template match="sentence"> 
    <p> 
        <xsl:call-template name="hilite">
            <xsl:with-param name="text" select="."/>
            <xsl:with-param name="search-string" select="$search"/>
        </xsl:call-template>
    </p> 
</xsl:template> 

<xsl:template name="hilite">
    <xsl:param name="text"/>
    <xsl:param name="search-string"/>
    <xsl:choose>
        <xsl:when test="contains($text, $search-string)">
            <xsl:value-of select="substring-before($text, $search-string)"/>
            <mark>
                <xsl:value-of select="$search-string"/>
            </mark>
            <xsl:call-template name="hilite">
                <xsl:with-param name="text" select="substring-after($text, $search-string)"/>
                <xsl:with-param name="search-string" select="$search-string"/>
            </xsl:call-template>
        </xsl:when>
        <xsl:otherwise>
            <xsl:value-of select="$text"/>
        </xsl:otherwise>
    </xsl:choose>
</xsl:template>

看看下面的示例,该示例使用XPath 3.0 fn:analyze-string()在我看来比 xsl:analyze-string 更好,并且效果很好与Saxon 9.8 HE。我也首先尝试了michael的解决方案,但是在我的用例中它无法正常工作。

它也应该在子节点上工作,而不会破坏层次结构或松开尾巴。

   <xsl:template name="highlight">
        <xsl:param name="element"/>
        <xsl:param name="search" as="xs:string"/>
        <xsl:param name="flags" required="no" select="'im'" as="xs:string"/>

        <xsl:choose>
            <xsl:when test="empty($search) or $search eq ''">
                <xsl:value-of select="."/>
            </xsl:when>
            <xsl:otherwise>
                <xsl:for-each select="$element/node()">
                    <xsl:choose>
                        <xsl:when test=". instance of text()">
                            <xsl:for-each select="fn:analyze-string(., $search, $flags)/*">
                                <xsl:choose>
                                    <xsl:when test="local-name(.) eq 'non-match'">
                                        <xsl:value-of select="./text()"/>
                                    </xsl:when>
                                    <xsl:otherwise>
                                        <span class="highlighted">
                                            <xsl:value-of select="./text()"/>
                                        </span>
                                    </xsl:otherwise>
                                </xsl:choose>
                            </xsl:for-each>
                        </xsl:when>
                        <xsl:otherwise>
                            <xsl:call-template name="highlight">
                                <xsl:with-param name="element" select="."/>
                                <xsl:with-param name="search" select="$search"/>
                                <xsl:with-param name="flags" select="$flags"/>
                            </xsl:call-template>
                        </xsl:otherwise>
                    </xsl:choose>
                </xsl:for-each>
            </xsl:otherwise>
        </xsl:choose>
    </xsl:template>

仅针对xQuery,请参见:

xquery version "3.1";

module namespace functions = 'https://bdo.badw.de/functions';

declare function functions:highlight($element, $search) {
    element {local-name($element)} {
        for $e in $element/node()
        return
            if ($e instance of text() = true()) then
                for $match in fn:analyze-string($e, $search, 'im')/*
                return
                    if (local-name($match) eq 'non-match') then
                        $match/text()
                    else
                        <span class="highlighted">{$match/text()}</span>
            else
                functions:highlight($e, $search)
    }
};
