regexp

Strip component

string $node = "pCube1.f[2]";
string $no_component = match "^[^\.]*" $node;
// Result: "pCube1" //

Extract component or attribute, with '.'

string $node = "pCube1.f[2]";
string $component = match "\\..*" $node;
// Result: ".f[2]" //


string $nodeAttr = "blinn1.color";
string $attrName = match "\\..*" $nodeAttr;
// Result: ".color" //

Extract attribute name, without '.'

string $node = "pCube1.f[2]";
string $component = `substitute "^[^.]*\\." $node ""`;
// Result: "f[2]" //

string $nodeAttr = "blinn1.color";
string $attrName = `substitute "^[^.]*\\." $nodeAttr ""`;
// Result: "color" //

Extract parent UI control from full path

string $uiControl = "OptionBoxWindow|formLayout52|formLayout55|button6";
string $uiParent = substitute "|[^|]*$" $uiControl "";
// Result: OptionBoxWindow|formLayout52|formLayout55 //

Strip trailing Line Break (\n), if any.

string $path = "C:/AW/Maya5.0/bin/maya.exe";
string $filepart = match "[^/\\]*$" $path;
// Result: "maya.exe"

Strip numeric suffix

string $node = "pCube1|pCubeShape223";
string $noSuffix = match ".*[^0-9]" $node;
// Result: "pCube1|pCubeShape"

Extract numeric suffix

string $node = "pCube1|pCubeShape223";
string $suffix = match "[0-9]+$" $node;
// Result: "223" //

Extract short name of DAG or control path

string $dagPath = "pCube1|pCubeShape223";
string $shortName = match "[^|]*$" $dagPath;
// Result: pCubeShape223 //
