Mikul, I think the rule of thumb in developing your XML schema is to name elements after your object types and represent object properties as element content, either attributes or elements. So, most people would design xml as <dir name="..."/> and <file name="..."/>. Imagine flikr or picasaweb XML, they'll go for <album title="..."/> and <picture caption="..."/>. This way they can preserve user chosen title and caption. If you design your XML as dir/@name and file/@name, it would make your XPath queries look natural, making it easier to search your XML and write an stylesheet for HTML rendering. For example, to find directories with pictures, you would use XPath "dir[contains(file/@name, '.jpg')]" or convert a file to a table row, you would write the following template: <xsl:template match="file"> <tr><td><xsl:value-of select="@name"/></td></tr> </xsl:template> -- Nicholas Sushkin, Senior Software Engineer http://www.openfinance.com http://www.wealthinformationexchange.com
