64 64  Local variable is a type of variable that can be newly created and used for a certain need.
65 65  
66 66  So as to create a local variable "newVar" with a value equals to "var number 1", we should write this piece of XSL code :
67 67  
81 +
68 68  {{code language="XML"}}
69 -<xsl:value-of select=" ixf:SetVar('newVar', 'var Number 1')"></xsl:value-of>
83 +<xsl:value-of select=" ixf:SetVar('newVar', 'var Number 1','false')"></xsl:value-of>
70 70  
71 71  {{/code}}
72 72  
87 +=== Explanation: ===
88 +
89 +* ixf:SetVar: Presumably a custom function or extension function that sets a variable.
90 +* 'newVar': The name of the variable being created.
91 +* 'var Number 1': The value assigned to the variable.
92 +* 'false': The third argument determining whether the variable is global (true) or local (false). if the argument equals true so this means we can get the variable from the parent scenario.
93 +
73 73  The call of this new variable in the scenario is similar to previous system variables:  **${newVar}.**
74 74  
75 75  To get 'newVar' inside an XSL file :
76 76  
98 +
77 77  {{code language="XML"}}
78 78  <xsl:value-of select="ixf:getVar('newVar')"></xsl:value-of>
79 79  {{/code}}

106 +To call a variable inside a connector, we should put it inside ${}. Eg: for a variable named ‘Var’, it can be called as ${Var}.
107 +
108 +For the condition in the connector's property, to check if the variable verify the condition, we can use " VarName== 'Value' " or " VarName!='Value' ".
109 +
110 +To call a variable in an xsl file, we should use the local variables SetVar ou GetVar.
