继续这个链接xslt返回以下兄弟姐妹的选择 我想知道,这里,这个的目的是什么generate-id以及它在这个匹配协议中是如何理解的.

<xsl:for-each select="/items/item[@lcn='005417714']">
  <xsl:for-each select="following-sibling::*[generate-id(preceding-sibling::item[@lcn != ''][1]) = generate-id(current())]">
  </xsl:for-each>
</xsl:for-each>

任何想法,请分享.

我在我的HTML文件中遇到过这种代码,在这里,我只想了解这个data-bind属性及其属性values(例如:) visible: tabs.active().value === 'sourceXml'.它在这做什么？任何人都善意解释.

<div style="border: solid #ddd; border-width: 0 1px 1px 1px; padding: 16px 12px 8px 12px; margin-top: -20px">
    <div data-bind="visible: tabs.active().value === 'sourceXml'">
    <div data-bind="template: { name: 'sourceXml', data: sourceXml }"></div>
</div>

<div data-bind="visible: tabs.active().value === 'searchTerms'">
    <div data-bind="template: { name: 'searchTerms', data: searchTerms }"></div>
</div>

<div data-bind="visible: tabs.active().value === 'outputFormat'">
    <div data-bind="template: { name: 'outputFormat', data: outputFormat }"></div>
</div>

<div data-bind="visible: tabs.active().value === 'savedQueries'">
    <div data-bind="template: { name: 'savedQueries', data: savedQueries …

我的XSLT中有两个场景:

<xsl:template match="/para/item"></xsl:template> 

和

<xsl:template match="para/item"></xsl:template> 

这两者有什么区别？

在这个简单的例子中,'return'用于三个地方.所以,我只是混淆了在函数中使用'return'.什么是使用这个'return'何时在函数内部使用？主要是,我需要知道,在提交按钮上,"返回"用于"onclick"属性,请参见此处<input type="submit" value="submit" onclick="return validateR();">.所以,也解释一下,'返回'究竟在这里做了什么.请.

<HTML>
    <HEAD>
        <TITLE>ComboBox Validation</TITLE>
        <script Language="JavaScript">
            function validateR(){
                var selectedCombobox = (comboForm.technology.value);
                if (selectedCombobox == "-1") {
                    alert("Please Select Technology");
                    return false; //here
                }
                if (selectedCombobox == "Servlet") {
                   alert("Yse");
                }
                return true; //here
            }
       </script>
   </HEAD>
 <BODY>
    <form name="comboForm">
        <select name="technology">
            <option value="-1">Select</option>
            <option value="JSP">Java Server Pages</option>
            <option value="Servlet">Servlet</option>
            <option value="PHP">PHP</option>
            <option value="ASP">ASP</option>
        </select>
        <input type="submit" value="submit" onclick="return validateR();">  //here
    </form>
 </BODY>
</HTML>

我有一个如下的XSLT并将此xslt应用到输入xml [粘贴在下面],它正常工作,除了需要澄清的一件事.

这是输入xml

<Test>
  <Experiment id='1'>
    <Dish1>
      <Conditions pressure='x' temp='y'/>
      <Measurement timeStamp='8am' reading='y'/>
    </Dish1>
    <Dish2>
      <Conditions pressure='x' temp='y'/>
      <Measurement timeStamp='8am' reading='y'/>
    </Dish2>
    <Dish1>
      <Conditions pressure='x' temp='y'/>
      <Measurement timeStamp='2pm' reading='y'/>
    </Dish1>
    <Dish2>
      <Conditions pressure='x' temp='y'/>
      <Measurement timeStamp='2pm' reading='y'/>
    </Dish2>
   </Experiment>
   <Experiment id='2'>
    <Dish1>
      <Conditions pressure='x' temp='y'/>
      <Measurement timeStamp='9am' reading='y'/>
    </Dish1>
    </Experiment>
</Test>

这是xslt

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
   <xsl:output method="xml" indent="yes"/>

   <xsl:template match="Experiment">
      <xsl:copy>
         <xsl:apply-templates select="@*" />
         <xsl:for-each-group select="*" group-by="local-name()">
            <xsl:copy>
               <xsl:apply-templates select="current-group()" />

            </xsl:copy>
         </xsl:for-each-group>
      </xsl:copy>
   </xsl:template>

   <xsl:template match="Experiment/*">
      <Observation>
         <xsl:apply-templates select="*/@*" …
