== Solutions Guide: XML Format and Parameters == The Fitting Guide file (data\fittingguide.xml) provides an automated way to adjust parameters based on proven adjustment settings, thus saving a lot of time, and getting consistent results. These settings are stored in an XML format, so that it can be easily adjusted or edited if necessary. Each file can contain several products (circuits) and their respective settings. Following are the different formats to express the different settings providing the information that the software uses for fitting hearing instruments. === Basic Structure === Sample File Structure:

=== Element Descriptions and Attributes ===
Element Attribute Description
<PROJECT>...</PROJECT>   Container for all circuits. It is the main file definition, the parent container for all elements.
<CIRCUIT>...</CIRCUIT>   Container for a circuit definition, the parent container for <ISSUES> and/or <ISSUE> elements.
  Code="CircuitCode" Code of circuit. This identifies and differentiates adjustments that might have the same name.
  Title="InstrumentModel" Name or title (to be displayed) for the circuit
<ISSUES>...</ISSUES> Title="subtitle" Container for several issues. Required only if defining 2 or more issues. For a single issue, simply use element <ISSUE> directly, without defining it within <ISSUES>...</ISSUES> elements.
<ISSUE>...</ISSUE> Title="subtitle" Container for a single issue, which contains one or more adjustments. Title displays a description of the issue.
<ADJUSTMENTS>...</ADJUSTMENTS>
 Code="CircuitCode AdjName" Container for serveral adjustments. CircuitCode must the the same code defined in <CIRCUIT>. AdjName can be any string that best describes the adjustment.
<ADJUSTMENT>... </ADJUSTMENT>   Container for a single adjustment, which could contains zero or more <STEP> elements.
  Row="RowNumber" Row (order) where to display it. Row numbering starts with 0. Eg: Row="0"
  Steps="NumSteps" The number of time(s) to apply a step before moving to the next one.
  Action="val" val can be one of these:
Y Take action.
Eg: <ADJUSTMENT Row="1" Action="Y" Title="Set Gain">..</ADJUSTMENT>
N Take No action. Use this to simply display the specified title (with no action associated with it).
Eg: <ADJUSTMENT Row="3" Action="N" Title="TIPS"/>
  Title="Action Description" Title to display in row.
<STEP/>
   Container for a single step in an adjustment.
  Action="val" val can be one of these:
I Increase.
D Decrease.
EI Equation Increase.
ED Equation Decrease.
S Set a single value. Use with Value parameter.
RI Range Increase.
RD Range Decrease.
RS Range Set. Use with SetValues parameter.
  IncBy="numval" numval can be a positive or negative integer.
  SetValues="[x1,x2,x3,...,xN]" Set Range values. Use with Action="RS". Eg: SetValues="[5600,4500,4000]"
  Value="val" Set a single value. Use with Action="S". Eg: Value="Dynamic"
  GT="param2" Greater Than. If param1 > param2, perform Action. param1 would be the value of parameter ParamName specified in attribute Param. Use in conjunction with EQU attribute.
Eg: <STEP Action="ED" IncBy="-2" GT="LTH4" EQU="UTH4[GTE]LTH4" Param="UTH4"/>
  LT="param2" Lesser Than. If param1 < param2, perform Action. param1 would be the value of parameter ParamName specified in attribute Param. Use in conjunction with EQU attribute.
Eg: <STEP Action="ED" IncBy="-2" LT="max" EQU="min[LT]max" Param="min"/>
  EQ="param2" Equal To. If param1 >= param2, perform Action. param1 would be the value of parameter ParamName specified in attribute Param. Use in conjunction with EQU attribute.
  GTE="param2" Greater Than or Equal To. If param1 >= param2, perform Action. param1 would be the value of parameter ParamName specified in attribute Param. Use in conjunction with EQU attribute.
Eg: <STEP Action="ED" IncBy="-2" GTE="LTH4" EQU="UTH4[GTE]LTH4" Param="UTH4"/>
  LTE="param2" Less Than or Equal To. If param1 <= param2, perform Action. param1 would be the value of parameter ParamName specified in attribute Param. Use in conjunction with EQU attribute.
Eg: <STEP Action="ED" IncBy="-2" LTE="max" EQU="min[LTE]max" Param="min"/>
  PEQU="ProposedEquation" Proposed Equation. The Proposed value uses the new value of the current parameter Param to calculate the equation. In other words, perform Action, evaluate equation, and if it is True, permanently store the results of performed Action. Eg:
<STEP Action="EI" IncBy="1" PEQU="SquelchTh[LT]50" Param="SquelchTh"/>
  EQU="equation" Equation. Perform Action if equation is True. Eg: EQU="UTH3-LTH3[GT]LLGAIN3-HLGAIN3"

Comparison Operators inside of defined equations:
[GTE]=Greater Than and Equal To
[LTE]=Lesser Than and Equal To
[EQ]=Equal To
[GT]=Greater Than
[LT]=Lesser Than
  Param="ParamName" ParamName is a parameter name supported by the circuit. Eg: HFC, LFC, TK

=== Define an Adjustment === Element Name: ''...'' Parameters to be used: * ADJUSTMENTS (plural) Code: Code string for a category of Adjustments, rather than a single adjustment. It cannot have other adjustment parameters. Note: This code string is composed of CircuitCode + IssueTitle, and it is case sensitive. For example: if the Circuit Code is "P2" (case sensitive), and the Issue Title is "Feedback" (case sensitive), then the Adjustments Code would be "P2 Feedback". See the code:
<CIRCUIT Code="P2" Title="Paragon 2">
<ISSUE Title="Feedback">
<ADJUSTMENTS Code="P2 Feedback">
...some adjustments here...
</ADJUSTMENTS>
</ISSUE>
</CIRCUIT>
* ADJUSTMENT (singular) Row: row number in which it will be displayed. Each adjustment must start with row 0. * ADJUSTMENT (singular) Action: One of the following: * Y: Yes, it performs an action. If Action=Y, then the adjustment must contain at least one Step. * N: No, it does not perform an action. If Action=N, then there are no Steps included with the adjustment, since there is no action to perform. * ADJUSTMENT (singular) Title: Title or name to display for the adjustement. Requirements: * Must belong to an Issue, or in the case of a sub-Adjustment, must belong to an Adjustment. * May contain none, one or many Steps, depending on the parameters. * In the case of a super-adjustment, it must contain at least one sub-Adjustment.

=== Conditional Values based on Immediate IF (aka. inline IF) === ''Param'' can contain a result derived from an immediate IF. This allows more flexibility in handling parameters. Format: ''Param="expression1, expression2; expression3"'' If //expression1// is true, then use value from //expression2//, else use value from //expression3//. Example: <STEP Action="D" IncBy="-1" Param="ExternalVC,WidebandGain;VC"></STEP> == ezFIT 5.x Platform == * Add support for localization. For example:
