    Parse an XML file with an xmlReader

Demonstrate the use of xmlReaderForFile() to parse an XML file and dump the informations about the nodes found in the process. (Note that the XMLReader functions require libxml2 version later than 2.6.) reader1 <filename> reader1 test2.xml > reader1.tmp ; diff reader1.tmp reader1.res ; rm reader1.tmp Daniel Veillard see Copyright for the status of this software.

    use various APIs for the xmlWriter

tests a number of APIs for the xmlWriter, especially the various methods to write to a filename, to a memory buffer, to a new document, or to a subtree. It shows how to do encoding string conversions too. The resulting documents are then serialized. testWriter testWriter ; for i in 1 2 3 4 ; do diff writer.xml writer$$i.res ; done ; rm writer*.res Alfred Mickautsch see Copyright for the status of this software.

    Parse and validate an XML file to a tree and free the result

Create a parser context for an XML file, then parse and validate the file, creating a tree, check the validation result and xmlFreeDoc() to free the resulting tree. parse2 test2.xml parse2 test2.xml Daniel Veillard see Copyright for the status of this software.
