function searchItemByName(sourceObject, name) {
if (sourceObject['ItemName'] === name) {
return sourceObject;
}
if (sourceObject['ChildrenBillOfMaterials']) {
for (let i = 0; i < sourceObject['ChildrenBillOfMaterials'].length; i++) {
let targetObject = searchItemByName(sourceObject['ChildrenBillOfMaterials'][i], name)
if (targetObject !== null) {
return targetObject;
}
}
}
return null;
}
