XML Document Opened After a Long Time

Oxygen XML Developer opens an XML document after a long time. Why does it happen?

Usually the time necessary for opening an XML document is long when the whole content of your document is on a single line or the document size is very large. If the content is on a single line please enable the Format and indent the document on open preference from menu Options > Preferences > Editor > Format before opening the document. If the document is very large (above 30 MB) you should make sure that the minimum limit of document size that enables the support for editing large documents (the value of the option Optimize loading in the Text edit mode for files over) is less than the size of your document. If that fails and you get an Out Of Memory error (OutOfMemoryError) you should increase the memory available to Oxygen XML Developer .
