Re: [xsl] Help needed with converting to (patterned) Element content to sub-elements only

Hi,

That is easy with XSLT 2.0, see below:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:output indent="yes"/>
<xsl:template match="coordinate">
<FullCoordinates datum="WGS84">
<xsl:for-each select="tokenize(normalize-space(.), ' ')">
<xsl:variable name="values" select="tokenize(., ',')"/>
<Point longitude="{$values[1]}" latitude="{$values[2]}">
<xsl:if test="$values[3]"><xsl:attribute name="ht_above_geoid" select="$values[3]"/></xsl:if>
</Point>
</xsl:for-each>
</FullCoordinates>
</xsl:template>
</xsl:stylesheet>

on

<coordinate>
    aaa,bbb,ccc
    ddd,eee,fff  ggg,hhh    jjj,kkk,lll
</coordinate>

gives

<?xml version="1.0" encoding="UTF-8"?>
<FullCoordinates datum="WGS84">
   <Point longitude="aaa" latitude="bbb" ht_above_geoid="ccc"/>
   <Point longitude="ddd" latitude="eee" ht_above_geoid="fff"/>
   <Point longitude="ggg" latitude="hhh"/>
   <Point longitude="jjj" latitude="kkk" ht_above_geoid="lll"/>
</FullCoordinates>

Best Regards,
George

Hi,
I would really appreciate advice on the following task. My present version uses python,
but I would like to use XSLT.

The input file includes <coordinate> elements of the form
<coordinate>
aaa,bbb,ccc
ddd,eee,fff  ggg,hhh    jjj,kkk,lll
</coordinate>

of which the content, when left and right stripped, is a
whitespace-separated sequence of points; each point
being a comma-separated sequence of either two or three numbers.

All <coordinate> elements are to be replaced, in the output file, by
elements of the form:

<FullCoordinates datum="WGS84" >
 <Point longitude="aaa" latitude="bbb" ht_above_geoid="ccc">
 <Point longitude="ddd" latitude="eee" ht_above_geoid="fff">
 <Point longitude="ggg" latitude="hhh">
 <Point longitude="jjj" latitude="kkk" ht_above_geoid="lll">
</FullCoordinates>

Please note there is no 'height-above-geoid' attribute in the third <Point>.
