"""Drop <img> tags in article bodies whose file did not survive the recovery.
|
||
|
|
|
||
|
|
The same situation as assetcheck.py, one level down: the recovered bodies kept
|
||
|
|
their original /library/ references, and 22 of 200 point at files no archive
|
||
|
|
holds (checked against Wayback; the CDX API returns no captures for them).
|
||
|
|
|
||
|
|
Left alone they render as a broken-image box, which on a phone reads as an
|
||
|
|
unexplained 40px hole between paragraphs. The reference is still worth keeping
|
||
|
|
in the Markdown source, so this strips it only from the generated HTML and
|
||
|
|
leaves a comment naming the file, which keeps the output self-documenting for
|
||
|
|
anyone who later finds the originals on the offline drive.
