特别是,我想根据描述值修改每个placemark的样式部分。如果“描述”值为23,我希望用以下方式替换样式部分:
<LineStyle>
<color>ff0000ff</color>
</LineStyle>
<PolyStyle>
<fill>0.5</fill>
<color>ff0000ff</color>
</PolyStyle>
<LineStyle>
<color>ff0000ff</color>
</LineStyle>
<PolyStyle>
<fill>1</fill>
<color>#ffff99</color>
</PolyStyle>
ff0000ff
0.5
ff0000ff
否则,如果“描述”值为10,我希望以这种方式替换样式部分:
<LineStyle>
<color>ff0000ff</color>
</LineStyle>
<PolyStyle>
<fill>0.5</fill>
<color>ff0000ff</color>
</PolyStyle>
<LineStyle>
<color>ff0000ff</color>
</LineStyle>
<PolyStyle>
<fill>1</fill>
<color>#ffff99</color>
</PolyStyle>
ff0000ff

换句话说,我想根据描述值更改KML布局
请帮我设置XSL好吗?提前谢谢
编辑以遵循您的建议我包括了xslt文件,但它的格式不好。正如我所说,我不太擅长XSLT
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:kml="http://www.opengis.net/kml/2.2">
<xsl:output indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="@* | node()">
<xsl:for-each select="kml:Placemark">
<xsl:variable name="Value" select="@description"/>
<xsl:when test="$Value = '10'">
<xsl:element name="$Style">
<LineStyle>
<color>ff0000ff</color>
</LineStyle>
<PolyStyle>
<fill>1</fill>
<color>#ffff99</color>
</PolyStyle>
</xsl:element>
</xsl:when>
</xsl:for-each>
<xsl:copy>
<xsl:apply-templates select="@*| node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>

#ffff99
我建议使用单个模板来替换需要更改的部分,而不是一个大的choose/when块。例如:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
xmlns:kml="http://www.opengis.net/kml/2.2">
<xsl:output method="xml"/>
<!-- identity template copies nodes unchanged -->
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<!-- matches Style with sibling of description='23' -->
<xsl:template match="kml:Style[../kml:description='23']">
<Style>
<LineStyle>
<color>ff0000ff</color>
</LineStyle>
<PolyStyle>
<fill>0.5</fill>
<color>ff0000ff</color>
</PolyStyle>
</Style>
</xsl:template>
<!-- matches Style with sibling of description='10' -->
<xsl:template match="kml:Style[../kml:description='10']">
<Style>
<LineStyle>
<color>ff0000ff</color>
</LineStyle>
<PolyStyle>
<fill>1</fill>
<color>#ffff99</color>
</PolyStyle>
</Style>
</xsl:template>
</xsl:stylesheet>

这当然可以进一步细化,例如,如果您实际上只是在更改PolyStyle,那么您可以编写模板来匹配该元素。您到底在哪里处理这个问题?--另外,23和10是唯一可能的值吗?如果不是,那么当值不是这两个值时会发生什么呢?我从在线示例中尝试了几次编写xslt文件来实现这一点,但我不知道实现这一问题的基本语言语句。我仅将字符串('23'和'10')作为理解xslt结构的第一种简单而通用的方法,但理解如何计算相应的数字转换值也很有趣。例如,如何计算描述值(转换为数字)是否在25和50之间。thx for the patiencePost您的尝试,这样我们就可以修复它,而不必从头开始为您编写代码。@michael.hor257k ok posted
