Question

我有一个大型的xml文件（由Groundspeak.com生成），其中包含有关我所在地区位置的大量信息。

我希望能够将该数据的某些部分提取到新的csv文件，例如下面的例子。

<name>Isle of Man</name>
  <desc>Geocache file generated by Groundspeak</desc>
  <author>Groundspeak</author>
  <bounds minlat="54.04725" minlon="-4.81115" maxlat="54.401" maxlon="-4.3105" />
  <wpt lat="54.097833" lon="-4.6537">

      <groundspeak:long_description html="True">&lt;center&gt;&lt;font size="+2" color="#006600" face=
      "Arial"&gt;&lt;strong&gt;Hunter and Quarry&lt;/strong&gt; is a traditional
      cache which takes you on a stroll along a little used
      footpath next to Billown Quarry. After walking through the..

我需要的只是<wpt lat="54.097833" lon="-4.6537">和<desc>Hunter and Quarry by monstermunch, Traditional Cache (2/3)</desc>

采用以下格式：

-4.6537,54.097833，猎人和采石场

然后保存在csv文件中。

我在Mac上，有Sublime Text，不知道从哪里开始。

Answer 1

使用此XSLT行获得所需的结果：

<xsl:value-of select="concat(wpt/@lon,',',wpt/@lat,',',wpt/urlname)" />

<强>结果：

-4.6537,54.097833，猎人和采石场

如果您还需要在输入中处理,个字符，您可以使用以下命名模板CSVencode（这比上面的简单解决方案稍微复杂一点）：< / p>

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="text" version="1.0" encoding="UTF-8" indent="yes" omit-xml-declaration="yes" />

    <!-- Wrap Element   -->
    <xsl:template match="/root">
      <xsl:call-template name="CSV_encode">
        <xsl:with-param name="str" select="wpt/@lon" />
      </xsl:call-template>    
      <xsl:text>,</xsl:text>
      <xsl:call-template name="CSV_encode">
        <xsl:with-param name="str" select="wpt/@lat" />
      </xsl:call-template>    
      <xsl:text>,</xsl:text>
      <xsl:call-template name="CSV_encode">
        <xsl:with-param name="str" select="wpt/urlname" />
      </xsl:call-template>    
    </xsl:template>

    <xsl:template name="CSV_encode">
      <xsl:param name="str" />
      <xsl:variable name="str2">
        <xsl:call-template name="Quot_encode">
          <xsl:with-param name="str" select="$str" />
        </xsl:call-template>
      </xsl:variable>
      <xsl:choose>
        <xsl:when test="contains($str2,',')">
          <xsl:value-of select="concat('&quot;',$str2,'&quot;')" />        
        </xsl:when>
        <xsl:otherwise>
          <xsl:value-of select="$str2" />        
        </xsl:otherwise>
      </xsl:choose>    
    </xsl:template>

    <xsl:template name="Quot_encode">
      <xsl:param name="str" />
      <xsl:param name="outstr" />
      <xsl:choose>
        <xsl:when test="string-length($str) = 0">
          <xsl:value-of select="$outstr" />        
        </xsl:when>        
        <xsl:when test="starts-with($str,'&quot;')">
          <xsl:call-template name="Quot_encode">
            <xsl:with-param name="str"    select="substring($str,2)" />
            <xsl:with-param name="outstr" select="concat($outstr,'&quot;&quot;')" />
          </xsl:call-template> 
        </xsl:when>
        <xsl:otherwise>
          <xsl:call-template name="Quot_encode">
            <xsl:with-param name="str"    select="substring($str,2)" />
            <xsl:with-param name="outstr" select="concat($outstr,substring($str,1,1))" />
          </xsl:call-template>         </xsl:otherwise>
      </xsl:choose>    
    </xsl:template>

</xsl:stylesheet>
