You will need to create 3 files, as follows;
File Name: SimpleXMLStockScraper.xsl
<?xml version="1.0" ?>
- <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" version="2.0">
<xsl:output method="html" />
- <xsl:template match="stocks">
- <table border="1">
- <tr>
- <th>
<p>Symbol</p>
</th>
- <th>
<p>Last Trade Value</p>
</th>
- <th>
<p>Last Trade Date</p>
</th>
- <th>
<p>Last Trade Time</p>
</th>
- <th>
<p>Change</p>
</th>
- <th>
<p>Open</p>
</th>
- <th>
<p>Days Range High</p>
</th>
- <th>
<p>Days Range Low</p>
</th>
- <th>
<p>Volume</p>
</th>
</tr>
- <xsl:for-each select="stock">
- <tr>
- <td>
- <p>
<xsl:value-of select="symbol" />
</p>
</td>
- <td>
- <p>
<xsl:value-of select="last_trade_value" />
</p>
</td>
- <td>
- <p>
<xsl:value-of select="last_trade_date" />
</p>
</td>
- <td>
- <p>
<xsl:value-of select="last_trade_time" />
</p>
</td>
- <td>
- <p>
<xsl:value-of select="change" />
</p>
</td>
- <td>
- <p>
<xsl:value-of select="open" />
</p>
</td>
- <td>
- <p>
<xsl:value-of select="days_range_high" />
</p>
</td>
- <td>
- <p>
<xsl:value-of select="days_range_low" />
</p>
</td>
- <td>
- <p>
<xsl:value-of select="volume" />
</p>
</td>
</tr>
</xsl:for-each>
</table>
</xsl:template>
</xsl:stylesheet>
