Hi,
I am working on XSLT to convert one XML file to the another XML file.From one file I am getting the data which needs to be displayed in other XML file.Now the problem is in the dataXML I have some elements like below:
<alerts>
     <companyAlerts>
        <publication>
        </publication>
        <recommendation>
        </recommendation>
     </companyAlerts>
</alerts>

Now the problem is in the <companyAlerts> element either the <publication> or <recommendation> would be there.it means at a time only one tag would be there and depending on it I have to display the data in different format.So I want to know how I can check that which tag is there <publication> or <recommendation> ?Please help me with this.

You can write one template rule for each case:

<xsl:template match="companyAlerts[publication]">
 ...
</xsl:template>

<xsl:template match="companyAlerts[recommendation]">
 ...
</xsl:template>
