Parsing

<libxml/tree.h> <libxml/parser.h> 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.

xmlReader

<libxml/xmlreader.h> Parse and validate an XML file with an xmlReader Demonstrate the use of xmlReaderForFile() to parse an XML file validating the content in the process and activating options like entities substitution, and DTD attributes defaulting.

xmlReader

<libxml/xmlreader.h> 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.

xmlWriter

<libxml/encoding.h> <libxml/xmlwriter.h> Navigates a tree to print element names Parse a file to a tree, use xmlDocGetRootElement() to get the root element, then walk the document and print all the element name in document order. tree1 filename_or_URL tree1 test2.xml > tree1.tmp ; diff tree1.tmp tree1.res ; rm tree1.tmp Dodji Seketeli see Copyright for the status of this software.
