What does XML_TAGMATCH mean?
This error means an XML end tag was encountered without a corresponding opening tag. This indicates an imbalance in the XML document structure, preventing proper parsing and hierarchical understanding of the data.
Common Causes
- An XML end tag (e.g., </tag>) is present without a corresponding opening tag.
- A nesting error in the XML structure where a closing tag is unpaired.
- The configuration file has an incomplete or malformed XML structure.
- A deletion or modification error in the XML file leading to a missing start tag.
- The parser detects an imbalance in the tag hierarchy.
