Bases: BaseSingleActionAgent

Deprecated since version 0.1.0: Use create_xml_agent() instead.

Agent that uses XML tags.

Parameters:
  • tools – list of tools the agent can choose from

  • llm_chain – The LLMChain to call to predict the next action

Examples

from langchain.agents import XMLAgent
from langchain

tools = ...
model =

Create a new model by parsing and validating input data from keyword arguments.

Raises [ValidationError][pydantic_core.ValidationError] if the input data cannot be validated to form a valid model.

self is explicitly positional-only to allow self as a field name.

param llm_chain: LLMChain [Required]#

Chain to use to predict action.

param tools: List[BaseTool] [Required]#

List of tools this agent has access to.

Parameters:
Returns:

Action specifying what tool to use.

Return type:

return_stopped_response(early_stopping_method: str, intermediate_steps: List[Tuple[AgentAction, str]], **kwargs: Any) β†’ AgentFinish#

Return response when agent has been stopped due to max iterations.

Parameters:
  • early_stopping_method (str) – Method to use for early stopping.

  • **kwargs (Any) – User inputs.

Returns:

Agent finish object.

Return type:

AgentFinish

Raises:

ValueError – If early_stopping_method is not supported.

save(file_path: Path | str) β†’ None#

Save the agent.

Parameters:

file_path (Path | str) – Path to file to save the agent to.
