KML import.

[ozbigben]

Hi All

 

Trying a relatively simple import of two text fields from some kml data but there's a mistake I'm not picking up. While I don't get any errors, I also don't get any records created. Any help would be appreciated.

 

XSLT:

<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:output method="xml" version="1.0" encoding="iso-8859-1" indent="yes"/>

<xsl:template match="/">

<FMPXMLRESULT xmlns="http://www.filemaker.com/fmpxmlresult">
<ERRORCODE>0</ERRORCODE>
<PRODUCT BUILD="" NAME="" VERSION=""/>
<DATABASE DATEFORMAT="" LAYOUT="" NAME="" RECORDS="" TIMEFORMAT=""/>

<METADATA>
<FIELD NAME="POSTCODE" TYPE="TEXT" EMPTYOK="YES" MAXREPEAT=""/>
<FIELD NAME="SHAPE" TYPE="TEXT" EMPTYOK="YES" MAXREPEAT=""/>
</METADATA>

<RESULTSET FOUND="">

<xsl:for-each select="Document/Folder/Placemark">
<ROW MODID="" RECORDID="">
<COL><DATA><xsl:value-of select="name"/></DATA></COL>
<COL><DATA><xsl:value-of select="Polygon/outerBoundaryIs/LinearRing/coordinates"/></DATA></COL>
</ROW>
</xsl:for-each>

</RESULTSET>
</FMPXMLRESULT>

</xsl:template>
</xsl:stylesheet>

I see two problems with your stylesheet:

 

First, the root element of your XML source is <kml> so the reference to "Document/Folder/Placemark" doesn't find anything.

 

The other issue is that the root element (and consequently all of its children) lives in its own namespace, so you must define a prefix for this namespace and use it when calling any element - something like:

 

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:k="http://www.opengis.net/kml/2.2"
exclude-result-prefixes="k">

<xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes"/>

<xsl:template match="/">

<FMPXMLRESULT xmlns="http://www.filemaker.com/fmpxmlresult">
<ERRORCODE>0</ERRORCODE>
<PRODUCT BUILD="" NAME="" VERSION=""/>
<DATABASE DATEFORMAT="" LAYOUT="" NAME="" RECORDS="" TIMEFORMAT=""/>

<METADATA>
<FIELD NAME="POSTCODE" TYPE="TEXT" EMPTYOK="YES" MAXREPEAT=""/>
<FIELD NAME="SHAPE" TYPE="TEXT" EMPTYOK="YES" MAXREPEAT=""/>
</METADATA>

<RESULTSET FOUND="">

<xsl:for-each select="k:kml/k:Document/k:Folder/k:Placemark">
<ROW MODID="" RECORDID="">
<COL><DATA><xsl:value-of select="k:name"/></DATA></COL>
<COL><DATA><xsl:value-of select="k:Polygon/k:outerBoundaryIs/k:LinearRing/k:coordinates"/></DATA></COL>
</ROW>
</xsl:for-each>

</RESULTSET>
</FMPXMLRESULT>

</xsl:template>
</xsl:stylesheet>

Thanks for that. I now have a nice set of data for visualising survey response stats in Google maps and a good idea of which XML tutorials I need to do next
