herolab.XPath() Function
Note: This function can only be used in a Trusted Macro
• Introduced in version 1.5.0
Returns data results based on the passed in XPath expression from the XML statblock. This is a reliable and easier way to get stat data from a character than using regular expression parsing of Text stat blocks.
Usage
herolab.XPath(XPath)
herolab.XPath(XPath, id)Options Coming in 1.8
herolab.XPath(XPath, id, delim)
herolab.XPath(XPath, id, "json")Parameters
XPath- The XPath expression to evaluate against the XML statblock.id- The id of the token. Defaults to the Current Token.delim- Coming in 1.8. Custom delimiter for the returned results. Defaults to", ". If equal to"json", a JSON Array will be returned instead of a String List.
Returns the requested data.
Example
Get various values from Hero Lab data (which is in XML).
When dealing with more complicated text elements with potential delimiter conflicts, it will usually be better to request the JSON output.
[race = herolab.XPath('/document/public/character/race/@name')]
[alignment = herolab.XPath('/document/public/character/alignment/@name')]
[improvedInit = herolab.XPath('boolean(/document/public/character/feats/feat[starts-with(@name,"Improved Initiative")])')]Returns:
Human Neutral Good 1

==== Changes Coming in 1.8 ====
Sometimes the data desired from herolab contains commas or is otherwise incompatible with the [[String List]] format and default (comma) separator. In the following example, the list of spells retrieved includes one called "Delay Poison, Communal" - as we see in the default output, this element would be incompatible with the standard String List format.
<syntaxhighlight lang="mtmacro" line>
[h: vXPath = "/document/public/character/spellsmemorized/spell[contains(@name,'De')]/@name"]
Default: [r: herolab.XPath(vXPath)]<br />
Custom Delim: [r: herolab.XPath(vXPath, token.name, "|")]<br />
JSON: <pre>[r: json.indent(herolab.XPath(vXPath, currentToken(), "json"))]</pre>Returns:
Default: Delay Poison, Communal, Detect Magic, Detect Undead
Custom Delim: Delay Poison, Communal|Detect Magic|Detect Undead
JSON:
[
"Delay Poison, Communal",
"Detect Magic",
"Detect Undead"

Version Changes
- 1.8 - Added optional param for custom delimiter in returned results
