分享请教英语好的VR高手
本人看到一篇外文文章，其中的例子做不出来，不知为什么，请帮帮忙。那些例子的源码全摆在那里了，但不知是我英语不好，还是他没注明文件名，我竟做不出他所讲的效果。好惨啊。
这文章在：http://www.w3.org/TR/xslt 。其中文章中的D.2 Data Example所讲的例子做不出来。（网址是http://www.w3.org/TR/xslt#data-example）
切盼英语好的VR高手，帮我把那些例子打成包寄到我的信箱里：asanmail@163.com。谢谢。

我的英语还可以，我看了一下很少的几个单词不懂，不过我翻出来的不行，对XML不熟悉，要

就是下面这几段：有兴趣的可看看，是讲利用xsl转变xml为html、svg、vrml的。

D.2 Data Example
This is an example of transforming some data represented in XML using three different XSLT stylesheets to produce three different representations of the data, HTML, SVG and VRML.
The input data is:
<sales>
<division id="North">
<revenue>10</revenue>
<growth>9</growth>
<bonus>7</bonus>
</division>
<division id="South">
<revenue>4</revenue>
<growth>3</growth>
<bonus>4</bonus>
</division>
<division id="West">
<revenue>6</revenue>
<growth>-1.5</growth>
<bonus>2</bonus>
</division>
</sales>
The following stylesheet, which uses the simplified syntax described in [2.3 Literal Result Element as Stylesheet], transforms the data into HTML:
<html xsl:version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
lang="en">
<head>
<title>Sales Results By Division</title>
</head>
<body>
<table border="1">
<tr>
<th>Division</th>
<th>Revenue</th>
<th>Growth</th>
<th>Bonus</th>
</tr>
<xsl:for-each select="sales/division">
<!-- order the result by revenue -->
<xsl:sort select="revenue"
data-type="number"
order="descending"/>
<tr>
<td>
<em><xsl:value-of select="@id"/></em>
</td>
<td>
<xsl:value-of select="revenue"/>
</td>
<td>
<!-- highlight negative growth in red -->
<xsl:if test="growth < 0">
<xsl:attribute name="style">
<xsl:text>color:red</xsl:text>
</xsl:attribute>
</xsl:if>
<xsl:value-of select="growth"/>
</td>
<td>
<xsl:value-of select="bonus"/>
</td>
</tr>
</xsl:for-each>
</table>
</body>
</html>
The HTML output is:
<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Sales Results By Division</title>
</head>
<body>
<table border="1">
<tr>
<th>Division</th><th>Revenue</th><th>Growth</th><th>Bonus</th>
</tr>
<tr>
<td><em>North</em></td><td>10</td><td>9</td><td>7</td>
</tr>
<tr>
<td><em>West</em></td><td>6</td><td style="color:red">-1.5</td><td>2</td>
</tr>
<tr>
<td><em>South</em></td><td>4</td><td>3</td><td>4</td>
</tr>
</table>
</body>
</html>
The following stylesheet transforms the data into SVG:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns="http://www.w3.org/Graphics/SVG/SVG-19990812.dtd">
<xsl:output method="xml" indent="yes" media-type="image/svg"/>
<xsl:template match="/">
<svg width = "3in" height="3in">
<g style = "stroke: #000000">
<!-- draw the axes -->
<line x1="0" x2="150" y1="150" y2="150"/>
<line x1="0" x2="0" y1="0" y2="150"/>
<text x="0" y="10">Revenue</text>
<text x="150" y="165">Division</text>
<xsl:for-each select="sales/division">
<!-- define some useful variables -->
<!-- the bar's x position -->
<xsl:variable name="pos"
select="(position()*40)-30"/>
<!-- the bar's height -->
<xsl:variable name="height"
select="revenue*10"/>
<!-- the rectangle -->
<rect x="{$pos}" y="{150-$height}"
width="20" height="{$height}"/>
<!-- the text label -->
<text x="{$pos}" y="165">
<xsl:value-of select="@id"/>
</text>
<!-- the bar value -->
<text x="{$pos}" y="{145-$height}">
<xsl:value-of select="revenue"/>
</text>
</xsl:for-each>
</g>
</svg>
</xsl:template>
</xsl:stylesheet>
The SVG output is:
<svg width="3in" height="3in"
xmlns="http://www.w3.org/Graphics/SVG/svg-19990412.dtd">
<g style="stroke: #000000">
<line x1="0" x2="150" y1="150" y2="150"/>
<line x1="0" x2="0" y1="0" y2="150"/>
<text x="0" y="10">Revenue</text>
<text x="150" y="165">Division</text>
<rect x="10" y="50" width="20" height="100"/>
<text x="10" y="165">North</text>
<text x="10" y="45">10</text>
<rect x="50" y="110" width="20" height="40"/>
<text x="50" y="165">South</text>
<text x="50" y="105">4</text>
<rect x="90" y="90" width="20" height="60"/>
<text x="90" y="165">West</text>
<text x="90" y="85">6</text>
</g>
</svg>
The following stylesheet transforms the data into VRML:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<!-- generate text output as mime type model/vrml, using default charset -->
<xsl:output method="text" encoding="UTF-8" media-type="model/vrml"/>
<xsl:template match="/">#VRML V2.0 utf8
# externproto definition of a single bar element
EXTERNPROTO bar [
field SFInt32 x
field SFInt32 y
field SFInt32 z
field SFString name
]
"http://www.vrml.org/WorkingGroups/dbwork/barProto.wrl"
# inline containing the graph axes
Inline {
url "http://www.vrml.org/WorkingGroups/dbwork/barAxes.wrl"
}
<xsl:for-each select="sales/division">
bar {
x <xsl:value-of select="revenue"/>
y <xsl:value-of select="growth"/>
z <xsl:value-of select="bonus"/>
name "<xsl:value-of select="@id"/>"
}
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
The VRML output is:
#VRML V2.0 utf8
# externproto definition of a single bar element
EXTERNPROTO bar [
field SFInt32 x
field SFInt32 y
field SFInt32 z
field SFString name
]
"http://www.vrml.org/WorkingGroups/dbwork/barProto.wrl"
# inline containing the graph axes
Inline {
url "http://www.vrml.org/WorkingGroups/dbwork/barAxes.wrl"
}
bar {

y 9

name "North"
}
bar {

name "South"
}
bar {
