[−][src]Struct lol_html::html_content::Comment
An HTML comment rewritable unit.
Exposes API for examination and modification of a parsed HTML comment.
Methods
impl<'i> Comment<'i>
[src]
pub fn text(&self) -> String
[src]
Returns the text of the comment.
pub fn set_text(&mut self, text: &str) -> Result<(), CommentTextError>
[src]
Sets the text of the comment.
pub fn before(&mut self, content: &str, content_type: ContentType)
[src]
Inserts content
before the comment.
Consequent calls to the method append content
to the previously inserted content.
Example
use lol_html::{rewrite_str, comments, RewriteStrSettings}; use lol_html::html_content::ContentType; let html = rewrite_str( r#"<div><!-- foo --></div>"#, RewriteStrSettings { element_content_handlers: vec![ comments!("div", |c| { c.before("<!-- 42 -->", ContentType::Html); c.before("bar", ContentType::Text); Ok(()) }) ], ..RewriteStrSettings::default() } ).unwrap(); assert_eq!(html, r#"<div><!-- 42 -->bar<!-- foo --></div>"#);
pub fn after(&mut self, content: &str, content_type: ContentType)
[src]
Inserts content
after the comment.
Consequent calls to the method prepend content
to the previously inserted content.
Example
use lol_html::{rewrite_str, comments, RewriteStrSettings}; use lol_html::html_content::ContentType; let html = rewrite_str( r#"<div><!-- foo --></div>"#, RewriteStrSettings { element_content_handlers: vec![ comments!("div", |c| { c.after("Bar", ContentType::Text); c.after("Qux", ContentType::Text); Ok(()) }) ], ..RewriteStrSettings::default() } ).unwrap(); assert_eq!(html, r#"<div><!-- foo -->QuxBar</div>"#);
pub fn replace(&mut self, content: &str, content_type: ContentType)
[src]
Replaces the comment with the content
.
Consequent calls to the method overwrite previous replacement content.
Example
use lol_html::{rewrite_str, comments, RewriteStrSettings}; use lol_html::html_content::ContentType; let html = rewrite_str( r#"<div><!-- foo --></div>"#, RewriteStrSettings { element_content_handlers: vec![ comments!("div", |c| { c.replace("Bar", ContentType::Text); c.replace("Qux", ContentType::Text); Ok(()) }) ], ..RewriteStrSettings::default() } ).unwrap(); assert_eq!(html, r#"<div>Qux</div>"#);
pub fn remove(&mut self)
[src]
Removes the comment.
pub fn removed(&self) -> bool
[src]
Returns true
if the comment has been replaced or removed.
