从字符串中删除 HTML 个标签
Remove HTML tags from strings
我正在尝试使用 rvest 从 HTML 标签中提取文本数据。
数据：
[vc_row css_animation="" row_type="row" use_row_as_full_screen_section="no" type="full_width" angled_section="no" text_align="left" background_image_as_pattern="without_pattern"][vc_column][vc_column_text]\n\n<h6 class="button" style="padding: 0px 42%;">Description</h6>\n\n<ol>\n\n \t<li>Ideal for : Women</li>\n\n \t<li>Package Contents : 1 Pcs</li>\n\n \t<li>Fit Type : Regular, Relaxed, Classic and Slim Fit.</li>\n\n \t<li>Care Instructions : Machine Wash and Normal Wash.</li>\n\n \t<li>Occasion : Lough, Smart, Dressy, Business, Casual and Formal.</li>\n\n \t<li>Sleeve Type : Short sleeves, 3/4th Sleeves, Full Sleeves ,Kimono Sleeves and Off Shoulder.</li>\n\n \t<li>Browse our Brand In Love for more choices of Shrugs , Tops and T shirt and Western wear Collections.</li>\n\n \t<li>Care Instructions : Ensure washing the tee in cold water, don't iron directly on the print and don't dry in direct sunlight.</li>\n\n</ol>\n\n<img class="alignnone wp-image-858" src="https://justelite.in/wp-content/uploads/2020/06/art-size.jpg" alt="" />\n\n<h6 class="button" style="padding: 0px 42%;">Reviews</h6>\n\n[/vc_column_text][/vc_column][/vc_row]
我做的是：
html_text(read_html(as.character(data)))
我仍然得到 vc_row css_animation 和一些其他未删除的标签。
dput数据：

据我所知，您得到的 html 标签不正确，因为这些标签通常由“<”和“>”分隔（例如，< h1 >）。你的被 [ h1 ] 包围了。调整上面链接的功能，你可以这样做：
s <- structure(2L, .Label = c("", "[vc_row css_animation=\"\" row_type=\"row\" use_row_as_full_screen_section=\"no\" type=\"full_width\" angled_section=\"no\" text_align=\"left\" background_image_as_pattern=\"without_pattern\"][vc_column][vc_column_text]\n\n<h6 class=\"button\" style=\"padding: 0px 42%;\">Description</h6>\n\n<ol>\n\n \t<li>Ideal for : Women</li>\n\n \t<li>Package Contents : 1 Pcs</li>\n\n \t<li>Fit Type : Regular, Relaxed, Classic and Slim Fit.</li>\n\n \t<li>Care Instructions : Machine Wash and Normal Wash.</li>\n\n \t<li>Occasion : Lough, Smart, Dressy, Business, Casual and Formal.</li>\n\n \t<li>Sleeve Type : Short sleeves, 3/4th Sleeves, Full Sleeves ,Kimono Sleeves and Off Shoulder.</li>\n\n \t<li>Browse our Brand In Love for more choices of Shrugs , Tops and T shirt and Western wear Collections.</li>\n\n \t<li>Care Instructions : Ensure washing the tee in cold water, don't iron directly on the print and don't dry in direct sunlight.</li>\n\n</ol>\n\n<img class=\"alignnone wp-image-858\" src=\"https://justelite.in/wp-content/uploads/2020/06/art-size.jpg\" alt=\"\" />\n\n<h6 class=\"button\" style=\"padding: 0px 42%;\">Reviews</h6>\n\n[/vc_column_text][/vc_column][/vc_row]"
