XSL:用xml标记替换某些字符

这种转变

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:my="my:my" exclude-result-prefixes="my">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <my:uicontrols>
  <control>[Save]</control>
  <control>[Cancel]</control>
 </my:uicontrols>

 <xsl:key name="kHasControls" match="text()"
  use="boolean(document('')/*/my:uicontrols/*[contains(current(), .)])"/>

 <xsl:variable name="vControls" select="document('')/*/my:uicontrols/*"/>

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

 <xsl:template match="text()[key('kHasControls', 'true')]">
  <xsl:choose>
   <xsl:when test="not($vControls[contains(current(),.)])">
     <xsl:copy-of select="."/>
   </xsl:when>
   <xsl:otherwise>
    <xsl:call-template name="createControl"/>
   </xsl:otherwise>
  </xsl:choose>
 </xsl:template>

 <xsl:template name="createControl">
  <xsl:param name="pText" select="."/>

  <xsl:choose>
   <xsl:when test="not(contains($pText, '['))">
    <xsl:copy-of select="$pText"/>
   </xsl:when>
   <xsl:otherwise>
     <xsl:copy-of select="substring-before($pText, '[')"/>

     <xsl:variable name="vStartText" select=
     "concat('[', substring-after($pText, '['))"/>
     <xsl:variable name="vCtrl" select="$vControls[starts-with($vStartText,.)]"/>
     <xsl:choose>
      <xsl:when test="not($vCtrl)">
       <xsl:text>[</xsl:text>
       <xsl:call-template name="createControl">
         <xsl:with-param name="pText" select="substring($vStartText,1)"/>
       </xsl:call-template>
      </xsl:when>
      <xsl:otherwise>
       <uicontrol>
        <xsl:value-of select="translate($vCtrl,'[]','')"/>
       </uicontrol>

       <xsl:call-template name="createControl">
         <xsl:with-param name="pText" select="substring-after($vStartText, $vCtrl)"/>
       </xsl:call-template>
      </xsl:otherwise>
     </xsl:choose>
   </xsl:otherwise>
  </xsl:choose>
 </xsl:template>
</xsl:stylesheet>

当应用于所提供的XML文档时 :

<section>
    <title>Buttons</title>
    <orderedlist>
        <listitem>
            <para>Clicking on [Save] will attempt to save changes, then it navigates to <xref linkend="saved" xrefstyle="select: title"/>.</para>
        </listitem>
        <listitem>
            <para>Clicking on [Cancel] navigates to <xref linkend="noSave" xrefstyle="select: title"/>.</para>
        </listitem>
    </orderedlist>
</section>

产生想要的正确结果

<section>
    <title>Buttons</title>
    <orderedlist>
        <listitem>
            <para>Clicking on <uicontrol>Save</uicontrol><xref linkend="saved" xrefstyle="select: title"/>.</para>
        </listitem>
        <listitem>
            <para>Clicking on <uicontrol>Cancel</uicontrol><xref linkend="noSave" xrefstyle="select: title"/>.</para>
        </listitem>
    </orderedlist>
</section>

注意以下几点

1. 此解决方案仅替换控件名称的受控列表 "[Anything]" 没有任何问题(例如,我们想显示一个著名的XPath表达式——这样的表达式按定义有谓词:)

2. 钥匙的使用保证了更好的效率 "[" .

uicontrol 对于嵌套方括号(需要对平衡方括号和非平衡方括号进行解析)。

此样式表:

  </xsl:copy>
 </xsl:template>
 <xsl:template match="text()" name="replace" priority="1">

  <xsl:variable name="vMask" select="translate($pString,

    <xsl:call-template name="replace">

    </xsl:call-template>
   </xsl:otherwise>
  </xsl:choose>
 </xsl:template>
</xsl:stylesheet>

<section>
 <title>Buttons</title>
 <orderedlist>
  <listitem>
   <para>Clicking on <uicontrol>Save</uicontrol> will attempt to save changes, then it navigates to <xref linkend="saved" xrefstyle="select: title"></xref>.</para>
  </listitem>
  <listitem>
   <para>Clicking on <uicontrol>Cancel</uicontrol> navigates to <xref linkend="noSave" xrefstyle="select: title"></xref>.</para>
  </listitem>
 </orderedlist>
</section>

有了这个输入:

<text>
This is an opening bracket [ ? [Yes] [No]
This is a closing bracket ] ? [Yes] [No]
</text>

<text>
This is an opening bracket [ ? <uicontrol>Yes</uicontrol> <uicontrol>No</uicontrol>
This is a closing bracket ] ? <uicontrol>Yes</uicontrol> <uicontrol>No</uicontrol>
</text>

注意 :任何匹配的文本 \[[^\[\]]*\] 会被包装成 第二季

你可以和 contains , substring-before 和 substring-after

编辑-应该有用:
