Closes#1236. Partitions XML documents iteratively in most cases*, never
loading the entire tree into memory. This ends up being much faster.
(* The exception is when the argument `xml_path` is passed to filter
elements. I was not able to find a way in Python to compare XPaths while
streaming the elements, aside from writing a custom XPath parser. So the
shortest way forward was to bite the bullet and load the whole tree in
memory when filtering by XPath.)
Memory usage is about 20% of usage on `main` when processing a 470MB XML
file. Time to process is 10s vs 900s.
Output is slightly different, but appears to be an improvement, adding
lines of text that are skipped in current partitioning. No text is lost.
### Summary
Partial solution to #1185.
Related to #1222.
Creates decorator from `chunk_by_title` cleaning brick.
Breaks a document into sections based on the presence of Title elements.
Also starts a new section under the following conditions:
- If metadata changes, indicating a change in section or page or a
switch to processing attachments. If `multipage_sections=True`, sections
can span pages. `multipage_sections` defaults to True.
- If the length of the section exceeds `new_after_n_chars` characters.
The default is 1500. The **chunking function does not split individual
elements**, so it's possible for a section to exceed that threshold if
an individual element if over `new_after_n_chars characters`, which
could occur with a long NarrativeText element.
Combines sections under these conditions
- Sections under `combine_under_n_chars` characters are combined. The
default is 500.
### Testing
from unstructured.partition.html import partition_html
url = "https://understandingwar.org/backgrounder/russian-offensive-campaign-assessment-august-27-2023-0"
chunks = partition_html(url=url, chunking_strategy="by_title")
for chunk in chunks:
print(chunk)
print("\n\n" + "-"*80)
input()
### Summary
Closes#1229. Updates `partition_xml` so that the element type is
inferred on each leaf node when `xml_keep_tags=False` instead of
delegating splitting and partitioning to `partition_xml`. If
`xml_keep_tags=True`, the file is treated like a text file still and
partitioning is still delegated to `partition_text`.
Also adds the option to pass `text` as an input to `partition_xml`.
### Testing
Create a `parrots.xml` file that looks like:
```xml
<xml><parrot><name>Conure</name><description>A conure is a very friendly bird.
Conures are feathery and like to dance.</description></parrot></xml>
```
Run:
```python
from unstructured.partition.xml import partition_xml
from unstructured.staging.base import convert_to_dict
elements = partition_xml(filename="parrots.xml")
convert_to_dict(elements)
```
One `main`, the output is the following. Notice how the `<name>` tag
incorrectly gets merged into `<description>` in the first element.
```python
[{'element_id': '7ae4074435df8dfcefcf24a4e6c52026',
'metadata': {'file_directory': '/home/matt/tmp',
'filename': 'parrots.xml',
'filetype': 'application/xml',
'last_modified': '2023-08-30T14:21:38'},
'text': 'Conure A conure is a very friendly bird.',
'type': 'NarrativeText'},
{'element_id': '859ecb332da6961acd2fb6a0185d1549',
'metadata': {'file_directory': '/home/matt/tmp',
'filename': 'parrots.xml',
'filetype': 'application/xml',
'last_modified': '2023-08-30T14:21:38'},
'text': 'Conures are feathery and like to dance.',
'type': 'NarrativeText'}]
```
One the feature branch, the output is the following, and the tags are
correctly separated.
```python
[{'element_id': '5512218914e4eeacf71a9cd42c373710',
'metadata': {'file_directory': '/home/matt/tmp',
'filename': 'parrots.xml',
'filetype': 'application/xml',
'last_modified': '2023-08-30T14:21:38'},
'text': 'Conure',
'type': 'Title'},
{'element_id': '113bf8d250c2b1a77c9c2caa4b812f85',
'metadata': {'file_directory': '/home/matt/tmp',
'filename': 'parrots.xml',
'filetype': 'application/xml',
'last_modified': '2023-08-30T14:21:38'},
'text': 'A conure is a very friendly bird.\n'
'\n'
'Conures are feathery and like to dance.',
'type': 'NarrativeText'}]
```
Update `test_json` to not use auto partition due to dependencies. Previously, to run `test_json` requires full requirements installation library to read file types, including but not limited to, docx, pptx, as well as others. Therefore the test will raise error with base installation. With the update, this fix also add to other test files to check its invariant with `elements_to_json`.
