Parsing an XML Document the Easy Way
Once you've read an XML document into memory, like this...
var xmlDocHolder = new ActiveXObject("MSXML2.DOMDocument")
xmlDocHolder.load("http://www.davidwall.com\countryList.xml")
...you can begin to read elements of that document. The document
countrylist.xml contains, in part, this structure:
To refer to data, we refer to a nested series of arrays. The element
containing the data "Japan" would be referred to like this:
JapanNode = xmlDocHolder.childNodes[0].childNodes[1].childNodes[0]
That is, we want to refer to the first (0) element (officialName) of
the second (1) element (country) of the first (0) element
(countryList). The word "Japan" itself -- the data -- would be
referenced as:
JapanText = xmlDocHolder.childNodes[0].childNodes[1].childNodes[0].text

Either way you look at it Microsoft Data Center management did not follow standards or best practices in this failure. In which case it makes me wonder more about the outsourcing of corporate data much less personal data.
