escape-html-uri

escape-html-uri

The escape-html-uri function in XQuery returns a string that is safe to use within HTML URIs by escaping characters that have a special meaning in HTML, such as
&
,
<
,
>
,
"
, and
'
 with corresponding percent-encodings. This ensures the URI can be safely embedded in HTML attributes without breaking the markup.

Syntax

fn:escape-html-uri(uri)
The following table describes the argument for this command:
Argument
Required/Optional
Description
uri
Required
The URI string to be escaped for HTML usage.

Return Value

  • Returns a string with characters that are special in HTML URI contexts replaced by percent-encoded equivalents.
  • Ensures the URI string is safe for inclusion in HTML documents as part of a URI.

Examples

The following table lists some sample values and return values:
SAMPLE FUNCTION
OUTPUT
fn:escape-html-uri("foo<>\")
"foo%3C%3E%22"
fn:escape-html-uri("")
""

Additional information

  • The function is specifically designed to escape URIs within HTML contexts where certain characters need escaping to avoid breaking HTML syntax.
  • It only encodes characters that are significant in HTML URIs, different from general URI encoding.
  • Always returns an
    xs:string
