Question

我有一个像这样的XML结构：

<people>
  <person id="1" name="Sam" />
  <person id="2" name="Dan" />
</people>
<executives>
  <executive id="1" name="Sam" favorite="yes" />
  <executive id="3" name="Ian" />
</executives>

我需要引用人中的所有节点，但我需要首先查看管理员中具有收藏夹属性的节点，然后是其他节点。我想我需要以某种方式合并<xsl:apply-templates select="/people/person[/executives/executive/@id = @id]" /> 和<xsl:apply-templates select="/people/person[@favorite = 'yes']" />。

但我不知道如何。

Answer 1

您可以通过使用密钥按$("#drop-list-id").on('changed', function() { $.getJSON('/servlet/level=1').success(function(json) { ... }); });属性

查找管理人员来简化操作

name

然后，要获得高管中最喜欢的<xsl:key name="execs" match="executive" use="@name" />个节点，您可以使用这样的键

person

你会否定获得其他人的条件。

假设您有一个结构良好的XML（即带有根元素），请尝试使用此XSLT

<xsl:apply-templates select="person[key('execs', @name)/@favorite = 'yes']" />

Answer 2

以下内容可行：

<!-- your root here, which you didn't show in the question -->
<xsl:template match="/root">
   <xsl:apply-templates select="people" />
</xsl:template>

<xsl:template match="people">
    <xsl:apply-templates select="person" mode="fav"/>
    <xsl:apply-templates select="person" mode="other"/>
</xsl:template>

<xsl:template match="person[@id = ../../executives/executive[@favorite = 'yes']/@id]" mode="fav">
    <favorite>
        <xsl:copy-of select="." />
    <favorite>
</xsl:template>

<!-- not a favorite -->
<xsl:template match="person" mode="fav" />

<!-- not a non-favorite -->
<xsl:template match="person" mode="other" />

<xsl:template match="person[not(@id = ../../executives/executive[@favorite = 'yes']/@id)]" mode="other">
    <non-favorite>
        <xsl:copy-of select="." />
    <non-favorite>
</xsl:template>

有更好的方法可以使用密钥来编写这个（这个解决方案同时由Tim提供），但我认为这就足够了，除非你有一些非常大的列表使得直接查找太慢。

我用于输出的结构应根据您的需要进行调整。我使用了额外的元素来确保你收集正确的元素。

Answer 3

这是另一种看待它的方式：

XSLT 1.0

<root>
    <people>
      <person id="1" name="Adam" />
      <person id="2" name="Betty" />
      <person id="4" name="David" />
      <person id="5" name="Eve" />
      <person id="6" name="Frank" />
      <person id="7" name="George" />
    </people>
    <executives>
      <executive id="3" name="Cecil" favorite="yes" />
      <executive id="5" name="Eve" />
      <executive id="6" name="Frank" favorite="yes" />
    </executives>
</root>

测试输入

<?xml version="1.0" encoding="UTF-8"?>
<root>
   <people>
      <person id="6" name="Frank"/>
      <person id="1" name="Adam"/>
      <person id="2" name="Betty"/>
      <person id="4" name="David"/>
      <person id="5" name="Eve"/>
      <person id="7" name="George"/>
   </people>
   <executives>
      <executive id="3" name="Cecil" favorite="yes"/>
      <executive id="5" name="Eve"/>
      <executive id="6" name="Frank" favorite="yes"/>
   </executives>
</root>

<强>结果

            <script>
                $(document).ready(function () {
