將選擇節點的兄弟節點移動到新的父節點

Question

我在這里做了一些搜索，發現了一些與我的問題有關的問題，但我仍然遇到麻煩...（希望我可以添加一個新問題，而不是對現有問題進行評論......）

<?xml version="1.0"?>
<section>
    <title>Main Section</title>
    <para>Here is some text that is a child of a main section.</para>
    <para>Some more text.</para>
    <para>When a section has subsections, it should not have loose paragraphs before the first sub section. Those loose paras should be placed inside a comment element.</para>
    <section>
        <title>This is my subsection</title>
        <para>Text that is inside of the sub-section</para>
        <para>And some more sub section text.</para>
    </section>
</section>

我希望將/ section / para放在新創建的注釋節點中，如下所示：

<?xml version="1.0"?>
<section>
    <title>Main Section</title>
    <comment>
       <para>Here is some text that is a child of a main section.</para>
       <para>Some more text.</para>
       <para>When a section has subsections, it should not have loose paragraphs before the first sub section. Those loose paras should be placed inside a comment element.</para>
    </comment>
    <section>
        <title>This is my subsection</title>
        <para>Text that is inside of the sub-section</para>
        <para>And some more sub section text.</para>
    </section>
</section>

我嘗試了一些我發現搜索stackoverflow的建議，最接近的是在這里。

這是我正在使用的樣式表：

<?xml version='1.0'?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml"/>


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


<!-- paras that are children of a section that has direct para children and dircect section children -->
<xsl:template match="section[para][section]/para[1]">
    <comment>
        <xsl:apply-templates select="../para" mode="commentPara"/>

    </comment>
</xsl:template>

<xsl:template match="*" mode="commentPara">
    <xsl:call-template name="identity"/>
</xsl:template>

<xsl:template match="section[para][section]/para"/>


</xsl:stylesheet>

它正在輸出：

<?xml version='1.0' ?>
<section>
    <title>Main Section</title>



    <section>
        <title>This is my subsection</title>
        <para>Text that is inside of the sub-section</para>
        <para>And some more sub section text.</para>
    </section>
</section>

只需刪除我要包含在注釋標記中的段落。 我嘗試在我鏈接到的問題中通過樣式表逐行進行...任何想法？ 謝謝，bp

Answer 1

這是分組鄰道para元素。

問題是，在解決沖突的模板規則 ：因為兩者para匹配規則具有相同的優先級進口和相同的計算優先級，錯誤恢復機制可能會導致應用最后一個。

您需要在“first para child”規則中明確定義@priority ，如：

<xsl:template match="section[para][section]/para[1]" priority="1">
</

通過這樣的修改，輸出是：

<?xml version="1.0" encoding="UTF-16"?>
<section>
    <title>Main Section</title>
    <comment>
        <para>Here is some text that is a child of a main section.</para>
        <para>Some more text.</para>
        <para>When a section has subsections, it should not have loose paragraphs before the first sub section. Those loose paras should be placed inside a comment element.</para>
    </comment>
    <section>
        <title>This is my subsection</title>
        <para>Text that is inside of the sub-section</para>
        <para>And some more sub section text.</para>
    </section>
</section>

Answer 2

我會這樣做 ：

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

 <xsl:key name="kPreceding" match="para"
  use="generate-id(following-sibling::section[1])"/>

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

 <xsl:template match="section[preceding-sibling::para]">
  <comment>
   <xsl:apply-templates mode="copy"
        select="key('kPreceding', generate-id())"/>
  </comment>

  <xsl:call-template name="identity"/>
 </xsl:template>

 <xsl:template match=
  "para[following-sibling::section]"/>

 <xsl:template match="para" mode="copy">
  <xsl:call-template name="identity"/>
 </xsl:template>
</xsl:stylesheet>

當此轉換應用於提供的XML文檔時：

<section>
    <title>Main Section</title>
    <para>Here is some text that is a child of a main section.</para>
    <para>Some more text.</para>
    <para>When a section has subsections, it should not have loose paragraphs before the first sub section. Those loose paras should be placed inside a comment element.</para>
    <section>
        <title>This is my subsection</title>
        <para>Text that is inside of the sub-section</para>
        <para>And some more sub section text.</para>
    </section>
</section>

產生了想要的正確結果：

<section>
   <title>Main Section</title>
   <comment>
      <para>Here is some text that is a child of a main section.</para>
      <para>Some more text.</para>
      <para>When a section has subsections, it should not have loose paragraphs before the first sub section. Those loose paras should be placed inside a comment element.</para>
   </comment>
   <section>
      <title>This is my subsection</title>
      <para>Text that is inside of the sub-section</para>
      <para>And some more sub section text.</para>
   </section>
</section>

說明 ：

1. 身份規則（模板）“按原樣”復制每個節點。

2. 為壓倒一切的模板section有前置兄弟（S） para包裝所有這些兄弟姐妹與comment元素，然后調用自身的身份轉換。

3. 為方便起見，我們定義了一個鍵，該鍵匹配section元素之前的所有para元素和給定的generate-id() 。

4. 具有以下兄弟section的para元素通過覆蓋模板從身份規則的操作中排除，該模板根本不執行任何操作。

5. 最后，當在包裝器comment中輸出時，這樣的para元素在模式copy中處理，模式copy只是調用身份規則來進行復制。
