XSLT 1.0:转义双引号 [英] XSLT 1.0: escaping double quotes

问题描述

我有一个遵循此方案的 XML 文件:

I have a XML file following this scheme:

<translationData>
<product>
<attributeValue>
<value>1/4"</value>
<value1>1/4"</value1>
<currentValue>aaaa;bbbb</currentValue>
</attributeValue>
</product>
</translationData>

由于currentValue"中的分号，我需要转义分号和value"中的双引号.我可以通过将所有文本放在 qoutes 中来转义分号，如下所示:

because of the semicolon in "currentValue" i need to escape the semicolon AND the double quotes in "value". I am able to escape the semicolon by placing all text in qoutes as following:

XSLT

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="text" encoding="utf-8" />

  <xsl:param name="delim" select="';'" />
  <xsl:param name="quote" select="'&quot;'" />
  <xsl:param name="break" select="'&#xA;'" />

  <xsl:template match="/">
    <xsl:apply-templates select="translationData/product/attributeValue" />
  </xsl:template>

  <xsl:template match="attributeValue">
    <xsl:apply-templates />
    <xsl:if test="following::*">
      <xsl:value-of select="$break" />
    </xsl:if>
  </xsl:template>


  <xsl:template match="*">
    <!-- remove normalize-space() if you want keep white-space at it is -->

    <xsl:value-of select="concat($quote, translate(.,'&quot;','\&quot;'), $quote)" />
    <xsl:if test="following-sibling::*">
      <xsl:value-of select="$delim" />
    </xsl:if>
  </xsl:template>

  <xsl:template match="text()" />
</xsl:stylesheet>

但不知何故输出是:

"1/4\";"1/4\";"aaaa;bbbb"

"1/4\";"1/4\";"aaaa;bbbb"

代替

"1/4\"";"1/4\"";"aaaa;bbbb"

"1/4\"";"1/4\"";"aaaa;bbbb"

我哪里出错了?

我是 XML 和 XSLT 的新手，在处理这个特定案例时没有发现任何问题.

I am new to XML and XSLT and did not find any question handling this specific case.

推荐答案

translate() 函数只会用另一个单个字符替换每个单个字符.

The translate() function will only replace each single character with another single character.

要将单个字符 " 替换为两个字符的字符串\"，您需要使用命名递归模板或 - 如果您的处理器支持它 - 扩展功能例如 EXSLT str:replace().

To replace a single character " with a two-character string\" you need to use a named recursive template or - if your processor supports it - an extension function such as EXSLT str:replace().

以下是使用递归模板的示例:

Here's an example of using a recursive template:

...

<xsl:template match="*">
    <xsl:text>"</xsl:text>
    <xsl:call-template name="replace">
        <xsl:with-param name="text" select="."/>
    </xsl:call-template>
    <xsl:text>"</xsl:text>
    <xsl:if test="position()!=last()">
        <xsl:text>;</xsl:text>
    </xsl:if>
</xsl:template>

...

<xsl:template name="replace">
    <xsl:param name="text"/>
    <xsl:param name="searchString">"</xsl:param>
    <xsl:param name="replaceString">\"</xsl:param>
    <xsl:choose>
        <xsl:when test="contains($text,$searchString)">
            <xsl:value-of select="substring-before($text,$searchString)"/>
            <xsl:value-of select="$replaceString"/>
           <!--  recursive call -->
            <xsl:call-template name="replace">
                <xsl:with-param name="text" select="substring-after($text,$searchString)"/>
                <xsl:with-param name="searchString" select="$searchString"/>
                <xsl:with-param name="replaceString" select="$replaceString"/>
            </xsl:call-template>
        </xsl:when>
        <xsl:otherwise>
            <xsl:value-of select="$text"/>
        </xsl:otherwise>
    </xsl:choose>
</xsl:template>
