XML writing and parsing

XML documents can be managed from the IEC application as a tree of XML tags.

Each XML tag is represented by:

a tag name,
a list of attributes (name=value),
a contents (raw text),
a list of child tags.

A complete XML document is handled as its main tag.

XML functions are originally designed for working with text buffers. However, some additional functions have been added for dealing with XML files on disk as it may be helpful in other applications.

Attention

XML parsing and writing functions support only 8 bit encoding features. This can be UTF8 or ANSI (ISO-8859-1) encoding. Some text buffers handling functions provide conversion between UTF8 and ANSI formats.

There must be one instance of the XmlManager declared in your application for using these functions.

There must be one instance of the TxbManager declared in your application for using text buffers related functions.
