-title: strings.FindRESubmatch
-description: Returns a slice of all successive matches of the regular expression. Each element is a slice of strings holding the text of the leftmost match of the regular expression and the matches, if any, of its subexpressions.

-  signatures: ['strings.FindRESubmatch PATTERN INPUT [LIMIT]']
-aliases: [/functions/findresubmatch]
----
-
-By default, `findRESubmatch` finds all matches. You can limit the number of matches with an optional LIMIT argument. A return value of nil indicates no match.
-
-{{% include "functions/_common/regular-expressions.md" %}}
-
-## Demonstrative examples
-
-```go-html-template
-{{ findRESubmatch `a(x*)b` "-ab-" }} → [["ab" ""]]
-{{ findRESubmatch `a(x*)b` "-axxb-" }} → [["axxb" "xx"]]
-{{ findRESubmatch `a(x*)b` "-ab-axb-" }} → [["ab" ""] ["axb" "x"]]
-{{ findRESubmatch `a(x*)b` "-axxb-ab-" }} → [["axxb" "xx"] ["ab" ""]]
-{{ findRESubmatch `a(x*)b` "-axxb-ab-" 1 }} → [["axxb" "xx"]]
-```
-
-## Practical example
-
-This markdown:
-
-```text
-- [Example](https://example.org)
-- [Hugo](https://gohugo.io)
-```
-
-Produces this HTML:
-
-```html
-<ul>
-  <li><a href="https://example.org">Example</a></li>
-  <li><a href="https://gohugo.io">Hugo</a></li>
-</ul>
-```
-
-To match the anchor elements, capturing the link destination and text:
-
-```go-html-template
-{{ $regex := `<a\s*href="(.+?)">(.+?)</a>` }}
-{{ $matches := findRESubmatch $regex .Content }}
-```
-
-Viewed as JSON, the data structure of `$matches` in the code above is:
-
-```json
-[
-  [
-    "<a href=\"https://example.org\"></a>Example</a>",
-    "https://example.org",
-    "Example"
-  ],
-  [
-    "<a href=\"https://gohugo.io\">Hugo</a>",
-    "https://gohugo.io",
-    "Hugo"
-  ]
-]
-```
-
-To render the `href` attributes:
-
-```go-html-template
-{{ range $matches }}
-  {{ index . 1 }}
-{{ end }}
-```
-
-Result:
-
-```text
-https://example.org
-https://gohugo.io
-```

-
-The `s` flag causes `.` to match `\n` as well, allowing us to find an `h2` element that contains newlines.

-- Follow the capitalization rules published in the [Chicago Manual of Style]
-- Capitalize the first letter of every word
-- Capitalize the first letter of the first word
-- Disable the effects of the `title` function
-
-The last option is useful if your theme uses the `title` function, and you would prefer to manually capitalize strings as needed.

-To remove leading and trailing newline characters and carriage returns:
-
-```go-html-template
-{{ trim "\nfoo\n" "\n\r" }} → foo
-{{ trim "\n\nfoo\n\n" "\n\r" }} → foo
-
-{{ trim "\r\nfoo\r\n" "\n\r" }} → foo
-{{ trim "\r\n\r\nfoo\r\n\r\n" "\n\r" }} → foo
-```
-
-The `strings.Trim` function is commonly used in shortcodes to remove leading and trailing newlines characters and carriage returns from the content within the opening and closing shortcode tags.
-
-For example, with this markdown:
-
-```text
-{{</* my-shortcode */>}}
-Able was I ere I saw Elba.
-{{</* /my-shortcode */>}}
-```
-
-The value of `.Inner` in the shortcode template is:
-
-```text
-\nAble was I ere I saw Elba.\n
-```
-
-If authored on a Windows system the value of `.Inner` might, depending on the editor configuration, be:
-
-```text
-\r\nAble was I ere I saw Elba.\r\n
-```
-
-This construct is common in shortcode templates:
-
-```go-html-template
-{{ trim .Inner "\n\r" }}
-```

-Since Go templates are HTML-aware, `truncate` will intelligently handle normal strings vs HTML strings:
-
-```go-html-template
-{{ "<em>Keep my HTML</em>" | safeHTML | truncate 10 }} → <em>Keep my …</em>
-```
-
-{{% note %}}
-If you have a raw string that contains HTML tags you want to remain treated as HTML, you will need to convert the string to HTML using the [`safeHTML`]function before sending the value to `truncate`. Otherwise, the HTML tags will be escaped when passed through the `truncate` function.
