Macro expression $.cfgfile
This macro expression represents the value stored in the configuration file (
XML or
INI). See:
XML and INI configuration files structure description for $.cfgfile macro expression
Syntax:
$.cfgfile("id","value")
id = the compound value identifier (e.g. "a/b/c")
value = (optional) the backup value in case the referred value is not found
Obsolete syntax of macro expression:
$cfgfile:id,value
Example:
1) $.cfgfile("config/data/webportnumber",0)
- Obtains the value /data/webportnumber from the configuration file referred with the config identifier.
2) $.cfgfile("config/data/webportnumber",80)
- Obtains the value /data/webportnumber from the configuration file referred with the config identifier. If the value is not found in the file, then the backup value 80 is returned.
3) $.cfgfile("config/data/boiler1/webportnumber",0)
- Obtains the value of /data/boiler1/webportnumber from configuration XML file registered as config identifier. The expression allows to read the value from arbitrary hierarchical level (the boiler1 level is extra here).
