So it's impossible to make any comparison. > Likewise, which is better, a retailer Clearly that's just the same example with different element names. > Using the second approach all this information can be provided in the > XML document: It can be provided somewhere in either solution. > The XSLT is not hardcoded to add a specific set of attributes; Of course it is! It has the hardcoded assumption that someone has gone to the trouble of designing an xml format with exactly the same attribute names as html but using elements rather than xml attributes. I suppose it's possible someone has done that but unlikely. Far more likely is they just use the same attributes in which case you can just use <xsl:copy-of select="@*"/> or that the element names are different to the html attribute names in which case you need to encode a translation table in your conversion and "hardwire" specific names in the source and result document. In any case any features you can do with the second form you can clearly do with the equivalent 1st form, it just depends where the additional metadata is placed <imagedata> <image>images/mighty_oj.gif</image> <alt>...</alt> ... </imagedate> for example.
