    Evaluate XPath expression and prints result node set.

Shows how to evaluate XPath expression and register known namespaces in XPath context.

    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.

    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.

    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.

    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.)

    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. (Note that the XMLReader functions require libxml2 version later than 2.6.)

    Show how to extract subdocuments with xmlReader

Demonstrate the use of xmlTextReaderPreservePattern() to parse an XML file with the xmlReader while collecting only some subparts of the document. (Note that the XMLReader functions require libxml2 version later than 2.6.)
