### What problem does this PR solve? When parsing pptx files, some shapes do not contain the `shape_type` attribute, which causes the original code to throw an exception during extraction, leading to failure in content extraction. This optimization introduces handling logic for such anomalous shapes, providing a safer and more robust processing mechanism. ### Type of change - [ ] Bug Fix (non-breaking change which fixes an issue) - [ ] New Feature (non-breaking change which adds functionality) - [ ] Documentation Update - [x] Refactoring - [x] Performance Improvement - [ ] Other (please describe):
