XSL:用 &apos 替换单引号和双引号；和" [英] XSL: replace single and double quotes with ' and "

问题描述

我有一个 XSL，用于将一个 XML 转换为另一个 XML，例如:

I have a XSL which I am using to transform one XML to another like:

<xsl:value-of select="somestatement"/>

其中一些语句有单引号和双引号.例如:这是一个示例"字符串.我有'单引号'

where some statement has single quotes and double quotes. Ex: This is an "example" string. I have 'single quotes'

我想用 ' 替换单引号，用 " 替换双引号，以便输出字符串:

I want to replace single quotes with ' and double quotes with " so that output string will be :

This is an "example" string. I have 'single quotes'

有人可以为此提出解决方案吗?

Can someone please suggest a solution for this?

提前感谢您的帮助.

推荐答案

您需要为此调用命名递归模板.试试:

You need to call a named recursive template for this. Try:

<xsl:template name="escape-quotes">
    <xsl:param name="text"/>
    <xsl:param name="searchString">'</xsl:param>
    <xsl:param name="replaceString">&amp;apos;</xsl:param>
    <xsl:variable name="apos">'</xsl:variable>  
    <xsl:choose>
        <xsl:when test="contains($text,$searchString)">
            <xsl:call-template name="escape-quotes">
                <xsl:with-param name="text" select="concat(substring-before($text,$searchString), $replaceString, substring-after($text,$searchString))"/>
                <xsl:with-param name="searchString" select="$searchString"/>
                <xsl:with-param name="replaceString" select="$replaceString"/>
            </xsl:call-template>
        </xsl:when>
        <xsl:when test="$searchString=$apos">
            <xsl:call-template name="escape-quotes">
                <xsl:with-param name="text" select="$text"/>
                <xsl:with-param name="searchString">"</xsl:with-param>
                <xsl:with-param name="replaceString">&amp;quot;</xsl:with-param>
            </xsl:call-template>
        </xsl:when>
        <xsl:otherwise>
            <xsl:value-of select="$text" disable-output-escaping="yes"/>
        </xsl:otherwise>
    </xsl:choose>
</xsl:template>

调用模板的例子:

<output>
    <xsl:call-template name="escape-quotes">
        <xsl:with-param name="text">This is an "example" string. I have 'single quotes'.</xsl:with-param>
    </xsl:call-template>
</output>

结果:

<output>This is an &quot;example&quot; string. I have &apos;single quotes&apos;.</output>
