- Class name: LLMHWPReader
- Category: SALT/Language Toolkit/Readers
- Output node: False

LLMHWPReader节点旨在读取和处理HWP（韩国文字处理器）文件，这是一种在韩国广受欢迎的文字处理文件格式。该节点将HWP文件转换为适合在llama_index生态系统中进行进一步分析或处理的格式。

# Input types
## Required
- path
    - 指定要读取的HWP文档的文件路径。这个路径对于定位和访问文件以进行处理至关重要。
    - Comfy dtype: STRING
    - Python dtype: str

## Optional
- extra_info
    - 以JSON字符串格式提供额外的信息或参数，可能会影响HWP文件的处理方式，允许对文件进行自定义处理。
    - Comfy dtype: STRING
    - Python dtype: str

# Output types
- documents
    - 将处理后的HWP文件内容作为文档对象返回，可直接集成到llama_index生态系统中进行进一步分析或处理。
    - Comfy dtype: DOCUMENT
    - Python dtype: tuple


## Usage tips
- Infra type: `CPU`
- Common nodes: unknown
