How can I extract the html table from kml_description?

Forum|alt.badge.img

I am trying to get the attributes from a point layer in a KMZ file stored in a HTML table within kml_description...... 

I have tried using HTMLToXHTMLConverter, but the features always fail. Currently using FME 2013 SP3.  FME Data Inspector is able to read and list them under "Attributes". 

I followed the instructions from:

https://knowledge.safe.com/articles/19918/how-to-expose-feature-attributes-from-kml-tag.html

 Here is an example of the html code that comes between <description> and </description>

<html lang="en">
<head><meta charset="utf8"/><style> * { margin: 0; } html, body { height: 100%; margin: 0; padding: 0; } h2 { textalign: center; background: #e5eCf9; } #summaryData { fontfamily: 'Helvetica Neue', Arial, Helvetica, sansserif; fontsize: 12px; width: 350px; } #summaryData th{ paddingright: 20px; width: 40%; } .fire_title { background: #ffffff; marginbottom: 15px; } .box { textalign: left; padding: 1.5em; paddingtop: 1em; marginbottom: 1.5em; background: #e5eCf9; width: 100%; } .spacer { height: 15px; } </style></head>
<body>
<div id="summaryData"><h2>Friday, June 3, 2016</h2>
<table>
<tr><th>Type</th><td>WF</td></tr></table><h2>Totals</h2>
<table>
<tr><th>Area Burned</th><td>28.22 acres</td></tr><tr/>
<tr><th>CO2</th><td>17.91 tons</td></tr>
<tr><th>CO</th><td>2.44 tons</td></tr>
<tr><th>PM10</th><td>0.23 tons</td></tr>
<tr><th>VOC</th><td>0.57 tons</td></tr>
<tr><th>SO2</th><td>0.01 tons</td></tr>
<tr><th>NOX</th><td>0.01 tons</td></tr>
<tr><th>NH3</th><td>0.04 tons</td></tr>
<tr><th>CH4</th><td>0.12 tons</td></tr>
<tr><th>PM25</th><td>0.2 tons</td></tr>
</table></div></body></html>

Hi @colin_forsyth, I was able to convert your sample HTML doc to  an XHTML doc with the HTMLToXHTMLConvertor transformer. However, the schema is different from the example in the article that you linked, you therefore will have to define your own XQuery expression. e.g.

declare default element namespace "http://www.w3.org/1999/xhtml";
for $x in /html/body/div/table
for $y in $x/tr
return fme:set-attribute($y/th/text(), $y/td/text())

If the first table (Type: WF) is not necessary:

declare default element namespace "http://www.w3.org/1999/xhtml";
for $x in /html/body/div/table[2]/tr
return fme:set-attribute($x/th/text(), $x/td/text())

Thanks Takashi. It is working for me now with the XQuery.

Don't know if anyone else wants to take a crack at another difficult KML to parse: but I'm at a loss:

Hi @mwilliamson, Welcome to the FME Forum. I'd highly encourage you to post this as a separate New Question. That way you can provide more details on what information you'd like to parse out of the KML, in your scenario, and a new question will likely get more attention.
