我继承了一个相当难看的xsl脚本，并且对xslt的使用经验非常有限。我昨天得到了很多帮助，但仍然有点挣扎，所以我提供了整个xml和更好的想要输出的描述。
我认为通过将整个脚本包装在模板中并选择是一件非常麻烦的事情，因为当我进行建议的更改时我不断收到编译错误，而且因为我有点失明，所以我很清楚我缺乏足够的理解和获得它的时间，所以我真诚地感谢一些帮助。
在这个阶段，我只关心组件4 。一旦我坚持下去，我相信我将能够重写其余的剧本。
我得到的输出;
contactID,mediumCode,areaCode,communicationDetails
"0123456789","T","02","62881111"
"5290001890","T","02","92881781"

答案 0 :(得分：2)
试试这个（假设您希望每个mediumCode在一条单独的行上）：
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="text" media-type="text" encoding="UTF-8" indent="no" />
<xsl:param name="component"/>
<xsl:variable name="q" select="'"'" />
<xsl:variable name="c" select="', '" />
<xsl:template match="communication">
<xsl:choose>
<xsl:when test="$component=4">
<xsl:value-of select="concat($q,../../contactID,$q)" />
<xsl:apply-templates />
<xsl:text>
</xsl:text>
</xsl:when>
</xsl:choose>
</xsl:template>
<xsl:template match="mediumCode | areaCode | communicationDetails">
<xsl:value-of select="concat($c,$q,.,$q)" />
</xsl:template>
<xsl:template match="contactID" />
</xsl:stylesheet>
我为逗号和引号创建了全局变量，只是为了让它在concat函数调用中更容易阅读。
此样式表通过吐出communication它的concatID祖先来处理任何person元素，然后只应用模板，这将处理它的三个子元素。
下一个模板以相同的方式处理三个子元素，输出逗号后跟引号中的值。
最后一个模板阻止contactID自行输出。默认情况下，XSLT处理器将按顺序为XML树中的每个节点查找模板。如果没有此模板，它将采用其中文本节点的默认行为，这只是按原样输出。
如果您希望所有通信节点都在一行上，您可以这样做：
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="text" media-type="text" encoding="UTF-8" indent="no" />
<xsl:param name="component"/>
<xsl:variable name="q" select="'"'" />
<xsl:variable name="c" select="', '" />
<xsl:template match="person">
<xsl:choose>
<xsl:when test="$component=4">
<xsl:apply-templates />
<xsl:text> </xsl:text>
</xsl:when>
</xsl:choose>
</xsl:template>
<xsl:template match="contactID">
<xsl:value-of select="concat($q,.,$q)" />
</xsl:template>
<xsl:template match="mediumCode | areaCode | communicationDetails">
<xsl:value-of select="concat($c,$q,.,$q)" />
</xsl:template>
</xsl:stylesheet>
编辑：这是一个解决方案，在输出的每一行中产生一致数量的字段：
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="text" media-type="text" encoding="UTF-8" indent="no" />
<xsl:param name="component"/>
<xsl:variable name="q" select="'"'" />
<xsl:variable name="c" select="', '" />
<xsl:template match="communication[string-length(concat(mediumCode,areaCode,communicationDetails))!=0]">
<xsl:choose>
<xsl:when test="$component=4">
<xsl:value-of select="concat(
$q,../../contactID,$q,$c,
$q,mediumCode,$q,$c,
$q,areaCode,$q,$c,
$q,communicationDetails,$q,'
'
)" />
</xsl:when>
</xsl:choose>
</xsl:template>
<xsl:template match="contactID" />
</xsl:stylesheet>
答案 1 :(得分：1)
我已经改变了你的代码以避免迭代。您只需硬编码 communication元素的索引即可获取其他数据。我认为这在你的情况下是可以接受的。而且，我不知道你为什么使用normalize-space函数。如果输入文档中没有多个空格，则可以避免这种情况。
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="text" media-type="text" encoding="UTF-8" indent="no" />
<xsl:strip-space elements="*"/>
<xsl:param name="component" select="4"/>
<xsl:template match="medicare">
<xsl:choose>
<xsl:when test="$component=4">
<xsl:apply-templates select="person"/>
</xsl:when>
</xsl:choose>

<xsl:template match="person">
<xsl:value-of select="concat(
'"', contactID, '"', ', ', '"',
normalize-space(communications/
communication[1]/mediumCode), '"', ', ', '"',
normalize-space(communications/

<xsl:text>

结果是：
"0123456789", "T", "02", "62881111", "E", "john.smith@myisp.com.au", "M", "04140012225"
"5290001890", "T", "02", "92881781", "E", "rabina.smiley@ekit.com", "M", "04290012333"
下面是一种更简洁的方法，可以产生相同类型的输出（适用于您的用例非常接近您在问题中显示的数据的情况）：
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="text" media-type="text" encoding="UTF-8" indent="no" />
<xsl:strip-space elements="*"/>
<xsl:param name="component" select="4"/>
<xsl:template match="medicare">
<xsl:choose>
<xsl:when test="$component=4">
<xsl:apply-templates select="person"/>
</xsl:when>
</xsl:choose>
</xsl:template>
<xsl:template match="person">
<xsl:value-of select="concat(
'"', contactID, '"', ', ', '"')"/>
<xsl:apply-templates select="communications/communication/*"/>
<xsl:text>
</xsl:text>
</xsl:template>
<xsl:template match="communication/*">
<xsl:value-of select="concat(., '"')"/>
<xsl:if test="count(../following-sibling::communication) +
count(following-sibling::*)!=0">
<xsl:value-of select="concat( ', ', '"')"/>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
