Outputs

Output	Type	What it gives
json	string	The JSON text.

Snapshot.Diff

Diffs two GUID-keyed dictionaries: added/removed/changed keys (values compared by JSON equality; nested dictionary key order is ignored).

Inputs

Input	Type	Default	What it does
oldValue required	IDictionary	—	The older snapshot dictionary.
newValue required	IDictionary	—	The newer snapshot dictionary.

Outputs

Output	Type
addedKeys	string[]
removedKeys	string[]
changedKeys	string[]

Returns: Dictionary with "addedKeys", "removedKeys" and "changedKeys".

XML.Parse

Parses XML into dictionaries, lists and strings (attributes as "@name", repeated elements as lists, mixed text as "#text"). An element that occurs once is a dictionary or a text, the same element occurring twice is a list, so a graph tried on a file with several items can break on a file with one: name such elements in listElements (for example Task, Resource; or * for all) and they always come as a list. Dictionary.ValueAtPath reads nested results either way. DOCTYPE declarations are accepted but an external entity is never read from disk or the network.

Inputs

Input	Type	Default	What it does
xml required	string	—	The XML text to parse.
listElements	string	""	Names of elements that must always come as a list, even when the file holds only one of them; separated by commas or semicolons, or * for every element. Empty (default) keeps the rule that only repeated elements are lists.

Outputs

Output	Type	What it gives
value	any	The parsed value (dictionary of dictionaries/lists/strings).

XML.ReadFromFile

Reads an XML file into dictionaries, lists and strings, in the same shape as XML.Parse (attributes as "@name", repeated elements as lists, mixed text as "#text"). The encoding the file declares is honoured - UTF-8, UTF-16, Windows-1252 / ISO-8859-1 - so the accents of an MSP or P6 export survive; reading the file with Text.ReadFromFile and then XML.Parse would decode it as UTF-8 first. A relative path starts in the graph's folder.

Inputs

Input	Type	Default	What it does
path required	string	—	Path to the XML file. A relative path starts in the graph's folder.

Outputs

Output	Type	What it gives
value	any	The parsed value (dictionary of dictionaries/lists/strings), see XML.Parse.
