如何在 .XSLT （英语：XSLT）-解网

问：

所以这就是我需要 JavaScript 在 xslt 中创建一个数组的事情，这是我执行动画的脚本，目前我有一些测试 xml 数据是一个链，但我需要是动态的而不是静态链，我尝试过获取，并放入 <XLS：value-of select=“/QflowMessage/NewTickets”>但没有检索任何数据，目标是创建一个带有var NewTickets的数组，其中包含所有信息，有什么想法吗？

var xmlString =` <QflowMessage>
<NewTickets>
    <CallTicket>
        <NewTicket>1</NewTicket>
        <TicketLabel>Now Serving</TicketLabel>
        <TicketNumber>456201</TicketNumber>
        <LocationLabel>InfoApproach</LocationLabel>
        <LocationNumber>608</LocationNumber>
    </CallTicket>
        <CallTicket>
 <NewTicket>1</NewTicket>
            <TicketLabel>Now Serving</TicketLabel>
            <TicketNumber>ABC201</TicketNumber>
            <LocationLabel>InfoApproach</LocationLabel>
            <LocationNumber>601</LocationNumber>
        </CallTicket>
        <CallTicket>
            <NewTicket>1</NewTicket>
            <TicketLabel>Serving</TicketLabel>
            <TicketNumber>ABC8701</TicketNumber>
            <LocationLabel>InfoApproach</LocationLabel>
            <LocationNumber>701</LocationNumber>

var parser = new DOMParser();
var xml = parser.parseFromString(xmlString, "text/xml");
var newTickets = Array.from(xml.querySelector("NewTickets").querySelectorAll("CallTicket"));
var ding = new Audio('../Style/Content/sound/ding.mp3');
var isDingPlayed = false;

XSLT在哪里？

XSLT 3.0 支持将 JSON 对象和数组处理为 XDM/XPath 3.1 映射和数组;在浏览器中，您可以使用 SaxonJS（当前版本为 2.6）来使用 XSLT 3.0，完整的文档位于 https://www.saxonica.com/saxon-js/documentation2/index.html：

要运行 XSLT 3.0（从源代码），您需要一个样式表，例如

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  version="3.0"
  xmlns:xs="http://www.w3.org/2001/XMLSchema"
  xmlns:map="http://www.w3.org/2005/xpath-functions/map"
  exclude-result-prefixes="#all">
  
  <xsl:output method="json" indent="yes"/>

  <xsl:template match="/" name="xsl:initial-template">
    <xsl:sequence select="array { QflowMessage/NewTickets/CallTicket ! map:merge(*!map:entry(local-name(), if (. castable as xs:double) then number() else string() )) }"/>
  </xsl:template>
  
</xsl:stylesheet>

你可以用 JavaScript 运行它，如下所示：

const xslt = `<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  version="3.0"
  xmlns:xs="http://www.w3.org/2001/XMLSchema"
  xmlns:map="http://www.w3.org/2005/xpath-functions/map"
  exclude-result-prefixes="#all">
  
  <xsl:output method="json" indent="yes"/>

  <xsl:template match="/" name="xsl:initial-template">
    <xsl:sequence select="array { QflowMessage/NewTickets/CallTicket ! map:merge(*!map:entry(local-name(), if (. castable as xs:double) then number() else string() )) }"/>
  </xsl:template>
  
</xsl:stylesheet>`;

var xml = `<QflowMessage>
<NewTickets>
    <CallTicket>
        <NewTicket>1</NewTicket>
        <TicketLabel>Now Serving</TicketLabel>
        <TicketNumber>456201</TicketNumber>
        <LocationLabel>InfoApproach</LocationLabel>
        <LocationNumber>608</LocationNumber>
    </CallTicket>
        <CallTicket>
 <NewTicket>1</NewTicket>
            <TicketLabel>Now Serving</TicketLabel>
            <TicketNumber>ABC201</TicketNumber>
            <LocationLabel>InfoApproach</LocationLabel>
            <LocationNumber>601</LocationNumber>
        </CallTicket>
        <CallTicket>
            <NewTicket>1</NewTicket>
            <TicketLabel>Serving</TicketLabel>
            <TicketNumber>ABC8701</TicketNumber>
            <LocationLabel>InfoApproach</LocationLabel>
            <LocationNumber>701</LocationNumber>
        </CallTicket>
</NewTickets>
</QflowMessage>`;

var result = SaxonJS.XPath.evaluate(`transform(map {
  'stylesheet-text' : $xslt,
  'source-node' : parse-xml($xml),
  'delivery-format' : 'raw'
})?output`, null, { params : { xslt : xslt, xml : xml } });

console.log(result);

使用 Node .js命令行工具 https://www.npmjs.com/package/xslt3 您还可以将 XSLT 源代码预编译为 SEF/JSON（例如），然后可以使用较小的运行时库，获得更好的性能和异步处理：xslt3xslt3 -t -nogo -xsl:abovexslt.xsl -relocate:on -export:abovexslt.xsl.sef.json
