我有以下XML:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="disp.xsl"?>
<root>
<node type="a">
<value>4</value>
</node>
<node type="b">
<value>2</value>
</node>
<node type="a">
<value>3</value>
</node>
<node type="b">
<value>1</value>
</node>
</root
我想生成一个报告,该报告总计每种类型的值元素并保持运行总计。我想,我想:
type: a total:7 cumulative total:7
type: b total:3 cumulative total:10
这是我的XSL:
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:key name="eachtype" match="node" use="@type" />
<xsl:template match="/root">
<html>
<body>
<xsl:for-each select="node">
Value: <xsl:value-of select="value"/> (Cumulative value: <xsl:variable name="temp" select="sum(preceding-sibling::node/value)+value"/><xsl:value-of select="$temp"/>)<br />
</xsl:for-each>
<hr />
<xsl:for-each select="node">
<xsl:variable name="thisType" select="@type"/>
type: <xsl:value-of select="$thisType" /> Value: <xsl:value-of select="value"/> (Cumulative value: <xsl:variable name="temp2" select="sum(preceding-sibling::node/value)+value"/><xsl:value-of select="$temp2"/>)<br />
</xsl:for-each>
<hr />
<xsl:for-each select="node[generate-id(.)=generate-id(key('eachtype',@type)[1])]">
<xsl:variable name="thisType" select="@type"/>
type: <xsl:value-of select="$thisType" /> Total: <xsl:value-of select="sum(/root/node[@type=$thisType]/value)"/> (Cumulative value: <xsl:variable name="temp2" select="sum(preceding-sibling::value)+value"/><xsl:value-of select="$temp2"/>)<br />
</xsl:for-each>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
产生以下输出:
Value: 4 (Cumulative value: 4)
Value: 3 (Cumulative value: 7)
Value: 2 (Cumulative value: 9)
Value: 1 (Cumulative value: 10)
--------------------------------------------------------------------------------
type: a Value: 4 (Cumulative value: 4)
type: a Value: 3 (Cumulative value: 7)
type: b Value: 2 (Cumulative value: 9)
type: b Value: 1 (Cumulative value: 10)
--------------------------------------------------------------------------------
type: a Total: 7 (Cumulative value: 4)
type: b Total: 3 (Cumulative value: 2)
我找不到在最后两行中获得累计总值的正确值的方法。是否有任何XSL资深人士可以帮助我尝试使用XSL?
答案 0 :(得分:3)
此转化:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:key name="kType" match="@type" use="."/>
<xsl:template match="/">
<xsl:for-each select=
"*/*/@type
[generate-id()
=
generate-id(key('kType', .)[1])
]">
<xsl:value-of select=
"concat('type: ', .,
' total: ', sum(/*/*[@type = current()]/value),
' cumulative total: ',
/*/*[@type = current()][last()]/value
+
sum(/*/*[@type = current()][last()]/preceding-sibling::*/value),
'
'
)
"/>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
应用于提供的XML文档:
<root>
<node type="a">
<value>4</value>
</node>
<node type="a">
<value>3</value>
</node>
<node type="b">
<value>2</value>
</node>
<node type="b">
<value>1</value>
</node>
</root>
生成想要的正确结果:
type: a total: 7 cumulative total: 7
type: b total: 3 cumulative total: 10
请注意此解决方案效率不高。刹车后我会提供一个更有效(递归)的。 :)
