我对 XML、XSLT 很陌生。我需要使用 XSLT 为我的数据捕获模板创建一个演示模板，以将其输出为 json。即，使用 XSLT 将 XML 文件转换为 JSON。
我正在使用以下 XSLT 将 XML 转换为 JSON：https ://github.com/bojanbjelic/xml2json/blob/master/xml2json.xsl
它工作得很好，但我真的很想扩展它，以便“OfferContent”字段中的文本转义双引号。
这是我的 XML：
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE data-capture-requirements SYSTEM "datacapture6.0.dtd">
<data-capture-requirements name="test" type="content">
<!-- data-capture-requirements elements contain area elements -->
<ruleset name="WebOffersDCT">
<script src="/iw/vanguard/CaaS/CaaSValidation.js" location="webserver" language="javascript"/>
<script><![CDATA[IWEventRegistry.addFormHandler("onFormInit", validatePageID);]]></script>
<description> Offers DCT</description>

这是我使用示例数据捕获记录的当前输出：
{"Offers_Config" : {"content" : {"ContentID" : "PC_1534", "landingSpot" : "LG_LOGON", "offerContent" : "<!--PPE: OfferId:PC_1475;LandingSpot:LG_LOGON --><a class="noborder" href="cbd:topicurl"><img style="border: none;" title="Vote in Vanguard's 2017 proxy campaign.

我的预期输出是：
{"Offers_Config" : {"content" : {"ContentID" : "PC_1534", "landingSpot" : "LG_LOGON", "offerContent" : "<!--PPE: OfferId:PC_1475;LandingSpot:LG_LOGON --><a class=\"noborder\" href=\"cbd:topicurl\"><img style=\"border: none;\" title=\"Vote in Vanguard's 2017 proxy campaign.

这里有一些很好的代码：XSLT + 用转义序列替换双引号。
<xsl:template name="escapeQuote">
<xsl:param name="pText" select="."/>
<xsl:if test="string-length($pText) >0">
<xsl:value-of select="substring-before(concat($pText, '"'), '"')"/>
<xsl:if test="contains($pText, '"')">
<xsl:text>\"</xsl:text>
<xsl:call-template name="escapeQuote">
<xsl:with-param name="pText" select="substring-after($pText, '"')"/>
</xsl:call-template>
</xsl:if>
</xsl:if>
</xsl:template>
但不幸的是，我对 XSLT 的经验不足，无法将它与我上面使用的代码集成。任何帮助将非常感激。提前致谢！
