Use the Basic method (default) where your watched site doesn't need Javascript to render.

The Chrome/Javascript method requires a network connection to a running WebDriver+Chrome server, set by the ENV var 'WEBDRIVER_URL'.

Tip: Connect using Bright Data and Oxylabs Proxies, find out more here.

If you're having trouble waiting for the page to be fully rendered (text missing etc), try increasing the 'wait' time here.
This will wait n seconds before extracting the text. {% if using_global_webdriver_wait %}

Activate preview
Pro-tips:
  • Use the preview page to see your filters and triggers highlighted.
  • Some sites use JavaScript to create the content, for this you should use the Chrome/WebDriver Fetcher
{% set field = render_field(form.include_filters, rows=5, placeholder=has_tag_filters_extra+"#example xpath://body/div/span[contains(@class, 'example-class')]", class="m-d") %} {{ field }} {% if '/text()' in field %} Note!: //text() function does not work where the <element> contains <![CDATA[]]>
{% endif %} One CSS, xPath, JSON Path/JQ selector per line, any rules that matches will be used.

Show advanced help and tips
{{ render_field(form.subtractive_selectors, rows=5, placeholder=has_tag_filters_extra+"header footer nav .stockticker //*[contains(text(), 'Advertisement')]") }}
  • Remove HTML element(s) by CSS and XPath selectors before text conversion.
  • Don't paste HTML here, use only CSS and XPath selectors
  • Add multiple elements, CSS or XPath selectors per line to ignore multiple parts of the HTML.

Text filtering

Limit trigger/ignore/block/extract to;
{{ render_checkbox_field(form.filter_text_added) }} {{ render_checkbox_field(form.filter_text_replaced) }} {{ render_checkbox_field(form.filter_text_removed) }} Note: Depending on the length and similarity of the text on each line, the algorithm may consider an addition instead of replacement for example.
 So it's always better to select Added+Replaced when you're interested in new content.
 When content is merely moved in a list, it will also trigger an addition, consider enabling Only trigger when unique lines appear
{{ render_checkbox_field(form.check_unique_lines) }} Good for websites that just move the content around, and you want to know when NEW content is added, compares new lines against all history for this watch.
{{ render_checkbox_field(form.remove_duplicate_lines) }} Remove duplicate lines of text
{{ render_checkbox_field(form.sort_text_alphabetically) }} Helps reduce changes detected caused by sites shuffling lines around, combine with check unique lines below.
{{ render_checkbox_field(form.trim_text_whitespace) }} Remove any whitespace before and after each line of text
{{ render_field(form.trigger_text, rows=5, placeholder="Some text to wait for in a line /some.regex\d{2}/ for case-INsensitive regex ") }}
  • Text to wait for before triggering a change/notification, all text and regex are tested case-insensitive.
  • Trigger text is processed from the result-text that comes out of any CSS/JSON Filters for this watch
  • Each line is processed separately (think of each line as "OR")
  • Note: Wrap in forward slash / to use regex example: /foo\d/
{{ render_field(form.ignore_text, rows=5, placeholder="Some text to ignore in a line /some.regex\d{2}/ for case-INsensitive regex ") }}
  • Matching text will be ignored in the text snapshot (you can still see it but it wont trigger a change)
  • Each line processed separately, any line matching will be ignored (removed before creating the checksum)
  • Regular Expression support, wrap the entire line in forward slash /regex/
  • Changing this will affect the comparison checksum which may trigger an alert
{{ render_field(form.text_should_not_be_present, rows=5, placeholder="For example: Out of stock Sold out Not in stock Unavailable") }}
  • Block change-detection while this text is on the page, all text and regex are tested case-insensitive, good for waiting for when a product is available again
  • Block text is processed from the result-text that comes out of any CSS/JSON Filters for this watch
  • All lines here must not exist (think of each line as "OR")
  • Note: Wrap in forward slash / to use regex example: /foo\d/
{{ render_field(form.extract_text, rows=5, placeholder="/.+?\d+ comments.+?/ or keyword") }}
  • Extracts text in the final output (line by line) after other filters using regular expressions or string match;
    • Regular expression ‐ example /reports.+?2022/i
    • Don't forget to consider the white-space at the start of a line /.+?reports.+?2022/i
    • Use //(?aiLmsux)) type flags (more information here)
    • Keyword example ‐ example Out of stock
    • Use groups to extract just that text ‐ example /reports.+?(\d+)/i returns a list of years only
    • Example - match lines containing a keyword /.*icecream.*/
  • One line per regular-expression/string match

{% if visualselector_enabled %} The Visual Selector tool lets you select the text elements that will be used for the change detection. It automatically fills-in the filters in the "CSS/JSONPath/JQ/XPath Filters" box of the Filters & Triggers tab. Use Shift+Click to select multiple items.

Sorry, this functionality only works with Playwright/Chrome enabled watches.

Enable the Playwright Chrome fetcher, or alternatively try our very affordable subscription based service.

This is because Selenium/WebDriver can not extract full page screenshots reliably.
