Re: XML parser to fetch default values of the optional attributes from the xsd file

Just use a standard XML parser to parse the XSD and the XML document. If you don't find the value in the XML document, then you can return the default value from the XSD. Alternatively, write an XSLT to add the default values into the document.

then you can return the default value from the XSD One would first need to identify the relevant schema definition for a given element or attribute. How do you propose to do that?	[reply]

ikegami: I assumed that if he (a) could detect that the defaults are missing, and (b) can track down the correct values, that he already knows how to identify the correct values. ...roboticus When your only tool is a hammer, all problems look like your thumb.	[reply]
Re^4: XML parser to fetch default values of the optional attributes from the xsd file by ikegami (Patriarch) on Jan 11, 2011 at 19:23 UTC
He's asking how to do (b), if not both (a) and (b), so it's not a very good assumption. Update: That was not very well put. The following explains what I meant. I would expect that he wants `get_attributes($ele)` to return all present attributes and all absent attributes for which the schema defines a default. To achieve that automatically, one must automatically determine (a) which attributes are missing and (b) what are the default for those attributes. Another scenario is that he simply wants `get_attribute($ele, 'foo')` to return the specified value for the attribute, or the default otherwise if it's not specified. To achieve that automatically, one must automatically determine (b) what is the default for that attribute. For both scenarios, you simply assumed the OP could already solve all but the trivial portions of his problem.	[reply] [d/l] [select]
