elloo,
I'm new to XML and XSLT and I've thought to learn more about it by trying do something basic. In this exercise I try to query the company.xml file using xpath and trying to save the result in result.xml.
When I run my code I get this in result.xml:
<?xml version="1.0" encoding="UTF-8"?>
<annual>
<company>
<turnover id="2001">100,000</turnover>
<turnover id="2002">200,000</turnover>
<turnover id="2003">300,000</turnover>
<employee id="001">Dicovery</employee>
</company>
<company>
<turnover id="2001">300,000</turnover>
<turnover id="2002">300,000</turnover>
<turnover id="2003">400,000</turnover>
<employee id="002">World</employee>
</company>
</annual>
However my output should be this in result.xml
<?xml version="1.0" encoding="UTF-8"?>
<annual>
<company>
<turnover id="2001">100,000</turnover>
<turnover id="2002">200,000</turnover>
<turnover id="2003">300,000</turnover>
<employee id="001">Dicovery</employee>
</company>
</annual>
########Here Is My Code###############
