Utility for extracting data from HTML tables.
This library allows you to parse tables from HTML documents and iterate over their rows. There are three entry points:
Table::find_first
finds the first table.Table::find_by_id
finds a table by its HTML id.Table::find_by_headers
finds a table that has certain headers.
Each of these returns an Option<
Table
>
, since there might not be any
matching table in the HTML. Once you have a table, you can iterate over it
and access the contents of each Row
.
§Examples
Here is a simple example that uses Table::find_first
to print the cells
in each row of a table:
let html = r#"
<table>
<tr><th>Name</th><th>Age</th></tr>
<tr><td>John</td><td>20</td></tr>
</table>
"#;
let table = table_extract::Table::find_first(html).unwrap();
for row in &table {
println!(
"{} is {} years old",
row.get("Name").unwrap_or("<name missing>"),
row.get("Age").unwrap_or("<age missing>")
)
}
If the document has multiple tables, we can use Table::find_by_headers
to identify the one we want:
let html = r#"
<table></table>
<table>
<tr><th>Name</th><th>Age</th></tr>
<tr><td>John</td><td>20</td></tr>
</table>
"#;
let table = table_extract::Table::find_by_headers(html, &["Age"]).unwrap();
for row in &table {
for cell in row {
println!("Table cell: {}", cell);
}
}
