我有一个要求，我必须读取一些数据，然后重新格式化，使数据的每一部分都在新行中。例如，我拥有的数据是：
dataLine1*dataLine2*dataLine3*dataLine4*dataLine5
我期望的结果是：
dataLine1
*dataLine2
*dataLine3
*.dataLine4
**dataLine5
因此，基本上，它可以归结为将*替换为"newlinecharater*"。然而，我仍然处于XSL的初学者水平，不确定如何实现这一点。
我的代码是：
<!-- START: Code to replace the data within a string since I am working on XSLT 0.1 -->
<xsl:template name="string-replace-all">
<xsl:param name="text" />
<xsl:param name="replace" />
<xsl:param name="by" />
<xsl:choose>
<xsl:when test="contains($text, $replace)">
<xsl:value-of select="substring-before($text,$replace)" />
<xsl:value-of select="$by" />
<xsl:call-template name="string-replace-all">
<xsl:with-param name="text"
select="substring-after($text,$replace)" />
<xsl:with-param name="replace" select="$replace" />
<xsl:with-param name="by" select="$by" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$text" />
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<!-- END: Code to replace the data within a string since I am working on XSLT 0.1 -->
<xsl:variable name="CPC" select="./_line_item_comment"/>
<xsl:variable name="newline"><xsl:text> </xsl:text></xsl:variable>
<xsl:variable name="myVar">
<xsl:call-template name="string-replace-all">
<xsl:with-param name="text" select="substring-after($CPC,'!$!')" />
<xsl:with-param name="replace" select="'*'" />
<xsl:with-param name="by" select="$newline" /> <!-- Here I have to give the newline character -->
</xsl:call-template>
</xsl:variable>
<xsl:value-of select="$myVar"/>
提前感谢！
最佳，
Shikhar

通常在HTML中，元素内部的换行符不会被呈现为换行符，这与XSLT无关，这只是HTML的工作方式。如果要在HTML中显式换行，请使用br元素，例如<br/>。因此，在您的模板中，用<xsl:copy-of select="$by"/>替换<xsl:value-of select="$by" />，并用<xsl:with-param name="by"><br/></xsl:with-param>调用模板，然后确保使用<xsl:copy-of select="$myVar"/>。
以下是经过调整的样本：
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="html"/>
<xsl:template name="string-replace-all">
<xsl:param name="text" />
<xsl:param name="replace" />
<xsl:param name="by" />
<xsl:choose>
<xsl:when test="contains($text, $replace)">
<xsl:value-of select="substring-before($text,$replace)" />
<xsl:copy-of select="$by" />
<xsl:call-template name="string-replace-all">
<xsl:with-param name="text"
select="substring-after($text,$replace)" />
<xsl:with-param name="replace" select="$replace" />
<xsl:with-param name="by" select="$by" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$text" />
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template match="/">
<xsl:variable name="CPC" select="./_line_item_comment"/>
<xsl:variable name="newline"><xsl:text> </xsl:text></xsl:variable>
<xsl:variable name="myVar">
<xsl:call-template name="string-replace-all">
<xsl:with-param name="text" select="substring-after($CPC,'!$!')" />
<xsl:with-param name="replace" select="'*'" />
<xsl:with-param name="by"><br/></xsl:with-param>
</xsl:call-template>
</xsl:variable>
<xsl:copy-of select="$myVar"/>
</xsl:template>
</xsl:transform>
另一种选择是，HTML将换行符呈现为<pre style="white-space: pre">...</pre>中的换行符。因此，如果你想使用现有的代码，那么使用例如
<pre style="white-space: pre"><xsl:value-of select="$myVar"/></pre>
