XML namespace indicates the usage range of XML names. Because XML can customize element tags, there is a high chance that XML names will overlap between different XML applications. Without a way to differentiate between names that don't apply, confusion would result. XML namespaces are designed to solve this problem. Through the XML namespace, we can distinguish the XML names from different XML applications. . Without a way to differentiate between names that don't apply, confusion would result. XML namespaces are designed to solve this problem. Through XML namespaces, we can distinguish elements and attributes with the same name from different XML applications. Related elements and attributes from a single XML application can be grouped together to facilitate software identification and processing. A namespace consists of a prefix and a local part, separated by a colon. The prefix identifies the namespace in which the element or attribute resides, and the local part identifies an element or attribute within the namespace. The entire name is also called the limit
