XML Document Takes a Long Time to Open

If Oxygen XML Editor takes a long time to open a document, check the following:

It takes longer to open an XML document if the whole content of your document is on a single line or if the document size is very large.

If the content is on a single line, you can speed up loading by enabling the Format and indent the document on open option. To do so, open the Preferences dialog box and go to Editor > Format > Format and indent the document on open.

If the document is very large (above 30 MB) make sure that the value of Optimize loading in the Text edit mode for files over) is greater than the size of your document.

If that fails and you get an Out Of Memory error (OutOfMemoryError) you can increase the memory available to Oxygen XML Editor.
