Re: [xsl] removing nodes to parent based on all child nodes not having text value

Ken....thank you so very much.  I believe this will work nicely.


In this case there only needs to be either <Individual> or <Business> under
<Entity>. Either the registration is for an individual or business. Both
should not exist in the same file. Because the business registration
information is being pulled from a legacy system certain information required
in the XML may not be available, such as <MailingAddressType/> and
<MailingAddressLine2/> as in the preceding example. However, if any descendant
element of a child has a text value such as <MailingAddressLine1>123
Street</MailingAddressLine1> it's parent and siblings all need to be copied
even if those siblings have no text value the nodes need to be copied.
Fine, that's a one line change, and the result is below.



If no descendant elements have a text value as is the case with <Individual>
that node and all descendant nodes of that element need to be stripped out.
Wow, I hope that wasn't too confusing.
Yes it wasn't too confusing. Having the example helps.



All the templates I have used thus far will strip out any element with no text
value, which removes the needed (dare I say required) elements of
<MailingAddressType/> and <MailingAddressLine2/> under the <Address> element.
I hope the code below helps. All I changed was the match criteria for the
elements that are preserved. It is all in how you say it! :{)}
