One aspect of the instant application facilitates detection of configuration anomaly. During operation, a system can convert a set of rules associated with configuration syntax information for a feature in a respective feature document to at least a structured regular expression. Then the system generates a set of configuration templates with a respective configuration template including the structured regular expression corresponding to the feature document. The system can select, based on a target configuration associated with the network device, a subset of the configuration templates and can extract, based on a match between the selected configuration templates and the target configuration, a set of features. The system can determine one or more rules associated with the extracted features. Based on the one or more rules the system can determine an anomaly in the target configuration and generate at least one recommended configuration to alleviate the anomaly.
