2: * section: xmlWriter
3: * synopsis: use various APIs for the xmlWriter
4: * purpose: tests a number of APIs for the xmlWriter, especially
5: * the various methods to write to a filename, to a memory
6: * buffer, to a new document, or to a subtree. It shows how to
7: * do encoding string conversions too. The resulting
8: * documents are then serialized.
9: * usage: testWriter
10: * test: testWriter ; for i in 1 2 3 4 ; do diff writer.xml writer$$i.res ; done ; rm writer*.res
