Add this script to a "Batch Script" editor (F10) and execute it with Script > Run.
The script compares all nodes against a given name, prints out a message if the name has been found, and selects the appropriate node. If the object does not exist you will also get a message.
The script's output is formatted and the name of the searched object is printed in quotes ("Cube03"). To do this, the escape character is used before the quote mark (\"):
checkForName = "Cube03"
nodeNames = []
nodeSelection = []
sceneNodes = scene.getNodes()
for entry in sceneNodes:
nodeNames.append(entry.getName())
if (checkForName in nodeNames):
scene.message("Object \""+checkForName+"\" exists.")
nodeSelection.append(scene.getNode(checkForName))
else:
scene.message("Object \""+checkForName+"\" ist not part of the project.")
scene.selectNodes(nodeSelection, True)
