Access the sources and problems companions of a sitemap result

sources() and problems() return the two companion tables the package produces alongside its tidy URL rows: the per-source fetch-metadata records and the non-fatal parse problems table. They dispatch on the object type, so the same call works on a read_sitemap() result and on a sitemap_audit() object:

Usage

sources(x, ...)

# Default S3 method
sources(x, ...)

# S3 method for class 'sitemap_audit'
sources(x, ...)

problems(x, ...)

# Default S3 method
problems(x, ...)

# S3 method for class 'sitemap_audit'
problems(x, ...)

Arguments

x

A read_sitemap() result (a tidy tibble carrying the sources/problems attributes) or a sitemap_audit() object.

...

Ignored; reserved for future methods.

Value

For sources(), the per-source fetch-metadata records; for problems(), the non-fatal parse problems table. A sitemap_audit() object always yields the documented (possibly zero-row) component; a read_sitemap() result yields its attached companion table.

Details

• On a read_sitemap() result, they read the sources / problems attributes the entry point attaches to the tidy tibble, so callers need not reach for attr().

• On a sitemap_audit() object, they return the first-class sources / problems components, delegating to audit_sources() / audit_problems() for identical behavior.

The default methods return the requested attribute (or NULL when the object carries none), so they are safe to call on any object.

audit_sources() and audit_problems() for the sitemap_audit component accessors.

Examples

xml <- paste0(
  '<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">',
  '<url><loc>https://example.com/</loc></url></urlset>'
)
path <- tempfile(fileext = ".xml")
writeLines(xml, path)
urls <- read_sitemap(path)
