SEARCH
Revision as of 12:35, 25 November 2010 by Td (talk | contribs) (→Syntax iMacros Browser IE Plug-in Firefox)
The SEARCH commands works with page source, instead of looking at the web page object model (DOM) that the TAG command uses. Thus SEARCH also "sees" e. g. comments in the page source code.
Syntax
SEARCH SOURCE=(TXT|REGEXP) IGNORE_CASE=YES EXTRACT=$1
Notes:
- The default is IGNORE_CASE=NO
- Extracted information is always of type text, as the SEARCH command works on the page source code. $1 refers to the Regular Expressions syntax. So the use of EXTRACT requires the use of the REGEX attribute.
- The REGEX attribute works with standard Regular Expressions (often called regex or regexp).
- iMacros for Firefox uses the Javascript regexp engine, which does not support lookbehind notation "(?<=ABC)".
Examples
Test macro: This macro checks for the presence of the Google Analytics script on our website and then extracts the ID of it.
URL GOTO=http://iopus.com/ 'Check for Script SEARCH SOURCE=TXT:"_gat._getTracker(\"UA-336765-1\")" 'Check for Script, ignore case SEARCH SOURCE=TXT:"_gettracker" IGNORE_CASE=YES 'Use regular expression to extract data SEARCH SOURCE=REGEXP:"_get[Tt]racker\\(([^)]+)\\)" EXTRACT="Tracker is $1" 'Display extracted data PROMPT {{!EXTRACT}}
Note: REGEXP:"_get[Tt]racker\\(([^)]+)\\)" means:
- find the word _get[Tt]racker, with T or t
- \\( - opening brace
- [^)]+ followed by anything except closing brace [^)] repeated one or more times +
- \\) and ending with closing brace
- => anything but not a closing brace is surrounded by capturing braces - ()
- => it extracts the argument of the gettracker command, that is the text between (...)
- The result is saved in $1, which is then assigned to the !EXTRACT variable
Another example: Search for a script. Escape " with \"
SEARCH SOURCE=TXT:"<script src=\"/js/datevalidator.js\""
