7Link your project with the AsmXml object file.
8 ~ ~ ~ ~
9Here are some tips to use it with various configurations:
10 MSVC 6: Add the \ms-coff\asm-xml.obj file to your project.
11 MinGW: Link your project with \ms-coff\asm-xml.obj.
12 Linux: Link your project with /elf/asm-xml.o.

230;[c]Element Map
231;[c]
232;[c] An element map is an array of 256 values each value correspond to
233;[c] an action to take corresponding to the current read char:
234;[c] * 1
235;[c] The character is invalid in the current state
236;[c]
237;[c] * Address % 4 = 0
238;[c] The address of the element map for the next char
239;[c]
240;[c] * Address % 4 = 1
241;[c] The address of the element class found preceded by the
242;[c] remaining chars and the type of class
243;[c] e.g.
244;[c] "bcd", 0, t, padding, ...
245;[c] * t = 0
246;[c] It is a collection, the pointer to the element class
247;[c] is at the next 4 byte align.
248;[c] * t = 1
249;[c] It is a text element, the text element class is stored
250;[c] after the padding.
251;[c]
252;[c] * Address % 4 = 3
253;[c] Same as previous but all chars have already been read.
254;[c] It is used when a name is the prefix of another name.
255;[c] e.g.:
256;[c] <ab>
257;[c] <abc>

4443;[c]Node
4444;[c]
4445;[c]A Node object is just a part of a tree that is a temporary object used to
4446;[c]build the maps of attributes/elements.
4447;[c]
4448;[c]The goal is to have an efficient implementation of a dictionary,
4449;[c]i.e. a set of name -> value.
4450;[c]
4451;[c]A null node pointer is an empty node. So a list is simply initialized
4452;[c]by clearing a register.
4453;[c]
4454;[c]A node is also a list of nodes, one for each char that can appear at this
4455;[c]level. The list of nodes is obtained by following the 'next' property.
4456;[c]
4457;[c]When a character matches, the 'succ' gives the next node for the next
4458;[c]possible character(s).
