Parse invalid XML
Parsing invalid XML involves a combination of corrective actions and flexible parsing techniques. One common approach is to use a lenient XML parser that can tolerate errors and retrieve information despite the malformed structure.
Corrective Actions:
Before parsing, consider pre-processing the XML to correct common errors. Tools like Tidy or Jsoup can help in cleaning and repairing XML documents.
Step-by-Step Implementation
Let’s walk through a step-by-step example of parsing invalid XML.
Step 1: Define Invalid XML
<root>
<element>Value</element>
<element>UnclosedTag
</root>
Step 2: Use Lenient Parser
- Create a DOMParser instance.
- Set the parser to be lenient using parser.setFeature().
- Parse the invalid XML using parser.parse().
How to Parse Invalid (Bad /Not Well-Formed) XML?
Parsing invalid or not well-formed XML can be a necessity when dealing with data from diverse sources. While standard XML parsers expect well-formed XML, there are strategies and techniques to handle and extract information from malformed XML documents.
In this article, we will explore how to parse such invalid XML using Java.
