Question

我有一个xml文件，root.xml：

 <?xml version="1.0" encoding="UTF-8"?>
    <statuses>
      <status topic-file="Procedure1">Complete</status>
      <status topic-file="Procedure3">Draft</status>
    </statuses>

请注意，我要跟踪4个程序。我想一次性改变2个程序的状态。我想要更改的内容在此XML文件statusByTitle.xml

中注明

<xsl:stylesheet version="2.0" 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
    <xsl:strip-space elements="*"/>

    <!-- set up the key -->
    <xsl:key name="statusByTitle" match="status" use="/topic-file" />

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

    <!-- use the key to set the attribute of the correct procedure -->

      <xsl:template 
         match="item[key('statusByTitle', status,  document('statusByTitle.xml'))]/@status">
      <xsl:attribute name="status">
        <xsl:value-of select="key('statusByTitle', ../status, document('statusByTitle.xml'))" />
    </xsl:attribute>
</xsl:template>

我想改变一次性指示的过程1和3的状态，所以我创建了这个XSLT转换：

<script>
$(document).ready(function() {
    var information_object = <?php echo json_encode($results); ?>;
    $(".content").click(function() {
        var info = information_object[$(this).data('id')];
        if (info) {
            var warning;
            if(info.status == 3){
                warning = "High Voltage Detected";
            }else if(info.status == 4){
                warning = "Caution is Recommended"
            }else{
                warning = "Ok";
            }
            Alert.render("temp: " + info.temp + "&#0153" + "<br>" + "Address: " + info.address + "<br>" + "Date: " + info.date + "<br>" + "Status: " + warning);
        } else {
            alert("Invalid ID: " + id);
        }
    });
});
</script>

 <script
    function CustomAlert(){
        this.render = function(dialog){
            var winW = window.innerWidth;
            var winH = window.innerHeight;
            var dialogoverlay = document.getElementById('dialogoverlay');
            var dialogbox = document.getElementById('dialogbox');
            dialogoverlay.style.display = "block";
            dialogoverlay.style.height = winH+"px";
            dialogbox.style.left = (winW/2) - (550 * .5)+"px";
            dialogbox.style.top = "100px";
            document.getElementById('dialogboxhead').innerHTML = "temp Warning Information";
            document.getElementById('dialogboxbody').innerHTML = dialog;
            document.getElementById('dialogboxfoot').innerHTML = '<button onclick="Alert.ok()">OK</button>';
        }

        this.ok = function(){
            document.getElementById('dialogbox').style.display = "none";
            document.getElementById('dialogoverlay').style.display = "none";
        }
    }

    var Alert = new CustomAlert();
</script>

我使用Saxon-HE 9.5.1.7在Oxygen中运行此转换，输出文件与输入文件相同。我已经盯着这一段时间，但却找不到错误。我以某种方式误解了键吗？

<xsl:key name="statusByTitle" match="status" use="/topic-file" />应<xsl:key name="statusByTitle" match="status" use="@topic-file" />。然后你有错误的元素名称item而不是procedure：

  <xsl:template 
         match="procedure[key('statusByTitle', @topic-file,  document('statusByTitle.xml'))]/@status">
      <xsl:attribute name="status" select="key('statusByTitle', ../@topic-file, document('statusByTitle.xml'))" />
</xsl:template>

所有更正我最终都是

<xsl:stylesheet version="2.0" 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
    <xsl:strip-space elements="*"/>

    <xsl:param name="status-url" select="'test2015080705.xml'"/>
    <xsl:param name="status-doc" select="doc($status-url)"/>

    <!-- set up the key -->
    <xsl:key name="statusByTitle" match="status" use="@topic-file" />

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

    <!-- use the key to set the attribute of the correct procedure -->

   <xsl:template 
         match="procedure[key('statusByTitle', @topic-file,  $status-doc)]/@status">
      <xsl:attribute name="status" select="key('statusByTitle', ../@topic-file, $status-doc)" />
   </xsl:template>

</xsl:stylesheet>
