我的智慧结束了这一点,并想知道这是否甚至可以用XSL。可以说我有这个XML数据:
<?xml version="1.0" standalone="yes"?>
<Data>
<Row>
<F1>Created By</F1>
<F2>City</F2>
</Row>
<Row>
<F1>John Doe</F1>
<F2>Los Angeles</F2>
</Row>
<Row>
<F1>Jane Doe</F1>
<F2>San Diego</F2>
</Row>
</Data>
我想在迭代其余数据时重复第一行元素。总之,我希望输出为:
[Created By] [City]
----------- ------------
[John Doe] [Los Angeles]
[Created By] [City]
---------- ------------
[Jane Doe] [San Diego]
最好的方法是什么?我尝试将第一个元素'Created By'设置为变量,但是当我尝试使用它时它不会渲染。我在XSL上很新,任何帮助都会受到赞赏。
谢谢

这是一个解决方案,与当前接受的答案不同,处理正确数据,其中包含各种未知的未知长度 - 请参阅处理无限数量列的更新,太强>:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:variable name="vMax1">
<xsl:call-template name="maxLength">
<xsl:with-param name="pNodes" select="/*/*/*[1]"/>
</xsl:call-template>
</xsl:variable>
<xsl:variable name="vMax2">
<xsl:call-template name="maxLength">
<xsl:with-param name="pNodes" select="/*/*/*[2]"/>
</xsl:call-template>
</xsl:variable>
<xsl:variable name="vLongest1" select=
"/*/*/*[1][string-length() = $vMax1][1]"/>
<xsl:variable name="vLongest2" select=
"/*/*/*[2][string-length() = $vMax2][1]"/>
<xsl:variable name="vUnderscores1" select=
"concat('__',
translate($vLongest1,translate($vLongest1, '_', ''),
'_________________________________________________________')
)"/>
<xsl:variable name="vUnderscores2" select=
"concat('__',
translate($vLongest2,translate($vLongest2, '_', ''),
'_________________________________________________________')
)"/>
<xsl:variable name="vBlanks1"
select="translate($vUnderscores1,'_', ' ')"/>
<xsl:variable name="vBlanks2"
select="translate($vUnderscores2,'_', ' ')"/>
<xsl:variable name="vTitle1" select=
"concat('[',/*/*/*[1],']',
substring($vBlanks1,1,
string-length($vBlanks1)-string-length(/*/*/*[1]))
)"/>
<xsl:variable name="vTitle2" select=
"concat('[',/*/*/*[2],']',
substring($vBlanks2,1,
string-length($vBlanks2)-string-length(/*/*/*[2]))
)"/>
<xsl:template match="Row">
<xsl:value-of select=
"concat('

<xsl:value-of select=
"concat('
',$vUnderscores1, ' ', $vUnderscores2, '
')"/>
<xsl:value-of select=
"concat(F1,
substring($vBlanks1,1,
string-length($vBlanks1)-string-length(F1)),
' ',
F2,
substring($vBlanks1,1,
string-length($vBlanks1)-string-length(F2)),
'
'
)"/>
</xsl:template>
<xsl:template name="maxLength">
<xsl:param name="pNodes" select="/.."/>
<xsl:for-each select="$pNodes">
<xsl:sort select="string-length()"
data-type="number" order="descending"/>
<xsl:if test="position() = 1">
<xsl:value-of select="string-length()"/>
</xsl:if>
</xsl:for-each>
</xsl:template>
<xsl:template match="Row[1]|text()"/>
</xsl:stylesheet>
在提供的XML文档上应用此转换时:
<Data>
<Row>
<F1>Created By</F1>
<F2>City</F2>
</Row>
<Row>
<F1>John Doe</F1>
<F2>Los Angeles</F2>
</Row>
<Row>
<F1>Jane Doe</F1>
<F2>San Diego</F2>
</Row>
</Data>
产生了想要的正确结果:
[Created By] [City]
____________ _____________
John Doe Los Angeles
[Created By] [City]
____________ _____________
Jane Doe San Diego
更有趣的是,当应用于此XML文档时:
<Data>
<Row>
<F1>Created By</F1>
<F2>City</F2>
</Row>
<Row>
<F1>John Doe</F1>
<F2>La Villa Real de la Santa Fe de San Francisco de Asis</F2>
</Row>
<Row>
<F1>Josiah Willard Gibbs</F1>
<F2>San Diego</F2>
</Row>
</Data>
再次生成正确的结果:
[Created By] [City]
______________________ _______________________________________________________
John Doe La Villa Real de la Santa Fe de San Francisco de Asis
[Created By] [City]
______________________ _______________________________________________________
Josiah Willard Gibbs San Diego
将此正确结果与当前接受的答案产生的结果进行比较:
Created By City
----------- -----------
John Doe La Villa Real de la Santa Fe de San Francisco de Asis
Created By City
----------- -----------
Josiah Willard GibbsSan Diego
II同一解决方案的XSLT 2.0变体:更短更容易编写:
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

<xsl:value-of select=
"string-join((for $i in 1 to $vNumCols,

),
' '
),
'

),
''

</xsl:template>
<xsl:template match="Row[1]|text()"/>
</xsl:stylesheet>
应用于此XML文档(3列):

请注意:
JLRishe提供的解决方案作为对其初始答案的更正,如果每行有4列,则将执行400次排序。

答案 1 :(得分:2)
这样就足够了:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="text"/>
<xsl:key name="kColumn" match="Row/*" use="count(preceding-sibling::*) + 1" />

在此输入上运行时:

<Row>
<F1>Jane Doe</F1>
<F2>La Villa Real de la Santa Fe de San Francisco de Asis</F2>
<F3>NM</F3>
</Row>
</Data>
它产生:
[Created By] [City] [Region]
---------------------------- ------------------------------------------------------- -------------
[Pablo Diego Ruiz y Picasso] [Los Angeles] [CA]
[Created By] [City] [Region]
---------------------------- ------------------------------------------------------- -------------
[Jane Doe] [La Villa Real de la Santa Fe de San Francisco de Asis] [NM]
答案 2 :(得分:1)
试试这个:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<!-- Output HTML - as an example -->
<xsl:output method="html" indent="yes"/>
<!-- Template that skips the first row, so it does not get processed -->
<xsl:template match="Row[position()=1]">
</xsl:template>
<!-- Template that process all rows except the first one -->
<xsl:template match="Row[position()>1]">
<!-- Copy the first row-->
<tr>
<xsl:for-each select="../Row[1]/*">
<td>
<xsl:value-of select="."/>
</td>
</xsl:for-each>
</tr>
<!-- Process this row -->
<tr>
<xsl:for-each select="*">
<td>
<xsl:value-of select="."/>
</td>
</xsl:for-each>
</tr>
</xsl:template>
<!-- Root template: output the HTML scaffolding and then processes the individual rows -->
<xsl:template match="/">
<html>
<head></head>
<body>
<table>
<xsl:apply-templates/>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
它输出一个HTML表格作为示例 - 它应该很容易适应其他输出。
