Comprehensive approach to handle dynamic elements effectively
These best practices help improve XPath or selector resilience against dynamic changes, ensuring more stable and uninterrupted RPA flows.
Best Practice | Description |
---|---|
Use Stable Attributes | Prioritize stable attributes such as id, name, or aria-label that are less likely to change across releases. Avoid using dynamically generated IDs or class names that can lead to unstable selectors. |
Prefer Relative XPaths | Avoid using absolute XPaths, as they are fragile and can easily break with changes to the DOM structure. Instead, use relative XPaths for greater flexibility and resilience. For example: //div[@id='user-section']//input[@type='text']. |
Leverage CSS Selectors | CSS selectors are generally more efficient and easier to read and maintain than XPaths. For example: div[id*='dynamic'] > span would find a span element within a div element whose ID contains the string "dynamic". |
Partial Attribute Matching | Use XPath functions such as contains(), starts-with(), and ends-with() to handle dynamic or partially known attribute values effectively. For example: //input[contains(@id, 'username')]. |
Utilize Stable Element Relationships | Preferably use stable nearby elements such as labels or containers to build robust relative selectors. For example: //label[text()='Email']/following-sibling::input |
Fallback Strategies | Use fallback options based on other attributes, text content, or DOM relationships to keep the automation running smoothly. Fall back options are required when the primary selector fails. |
