Keep Coding

I've been looking for a solution to this for some time now, but without success
I have an xml from an external source that holds information regarding thousands of products
XML sample:
<rss version="2.0" xmlns:g="http://base.google.com/ns/1.0">
<channel>
<title>Teste</title>
<link>http://www.teste.com.br</link>
<description>Com mais de 500.000...</description>
<item>
<title><![CDATA[Kit Teste Tamanho M]]></title>
<link><![CDATA[http://www.teste.com.br/kit-teste-tamanho-m]]></link>
<description><![CDATA[DESCRIÇÃO ​teste...]]></description>
<g:image_link>https://teste.com.br/800x800/123/12345/produto/12345/teste.jpg</g:image_link>
<g:price>99.99 BRL</g:price>
<g:sale_price>94.99 BRL</g:sale_price>
<g:condition>new</g:condition>
<g:availability><![CDATA[in stock]]></g:availability>
<g:id><![CDATA[SHAA-001]]></g:id>
<g:installment>
<g:months>10</g:months>
<g:amount>9.99 BRL</g:amount>
</g:installment>
<g:brand><![CDATA[Teste]]></g:brand>
<g:product_type><![CDATA[Teste > Teste]]></g:product_type>
<g:product_type><![CDATA[Teste > Teste > Teste]]></g:product_type>
<g:mpn><![CDATA[Teste]]></g:mpn>
<g:gtin><![CDATA[1234567891011]]></g:gtin>
<g:online_only>y</g:online_only>
</item>
</channel>
</rss>
And I need to show this information on a simple page.
HTML sample:
<table>
<tbody>
<tr>
<th>ID</th>
<th>GTIN</th>
<th>Title</th>
<th>Link</th>
<th>Price</th>
<th>Availability</th>
</tr>
<tr>
<td id="g:id"></td>
<td id="g:gtin"></td>
<td id="title"></td>
<td id="link"></td>
<td id="g:price"></td>
<td id="g:availability"></td>
</tr>
</tbody>
</table>
As I said, I have tried some ways to do this, but without success
Thanks in advance for any help.
