There is only one parameter you will need to specify, but you will need to enter two instances of it. /W – If you use this switch, FC will compress white space (tabs and spaces) during its comparison of your files./T – This switch will tell FC not to expand tabs to spaces.This is useful if you want to prevent two files from becoming extremely out of sync.

/ nnnn – Replacing the “n’s” here will tell FC that when it finds mismatched lines, it can only continue if it finds “n” consecutive matching lines after the mismatch.The default, if you do not specify a number is 100 lines of mismatched text. /LB n – Replace the “n” with a number to limit the amount of consecutive different lines that FC will read before it will abort./N – This switch can only be used with ASCII but it will show all the corresponding line numbers./L – This will compare your files as ASCII text./U – Use this switch to compare files as Unicode text files./A – This switch will make FC show only the first and last lines for each group of differences./C – If you need to do a case insensitive comparison, use this switch./B – This switch will perform a binary comparison.

A conventional software differencing utility would not pick up on this, but XMLSpy does.

An XML processor resolves entity references at run-time, so, although an XML file may not have changed, the entity definitions could have, resulting in a different XML file.

The XMLSpy XML differencing utility can be set to overlook irrelevant differences, whereas a conventional differencing utility cannot.

There are differences in XML when the ordering of child elements is irrelevant for example, if a schema defines a relationship using an "all" compositor, the ordering of child elements is immaterial.

XMLSpy accounts for this and intelligently ignores the attribute order, but a conventional differencing utility cannot and would therefore report every change in attribute ordering.

The order of XML attributes is irrelevant because XML processors do not consider the sequence that attributes appear in a particular element.

This change does not materially affect the contents of the XML document, and while a conventional software differencing utility would report that virtually every line of code in the XML instance document has changed, the XMLSpy XML compare utility will deal with this change appropriately. Suppose an XML developer changes the default namespace prefix in an XML instance document.The nature of XML means text-only compare tools fall short in these important scenarios:
