Syntax: REX expression, Replace expression, field to search, where to
store it
This provides alternate means of setting both the HTML fields
(Modify Date, Title, Description) and any
Additional Fields. It allows getting page information from
non-default places by searching and optionally replacing the data.
New blank rows will be provided as rows are used. See below for
examples.
REX Search - Allows you to specify a REX expression to narrow
down what contents of the From Field will be used. Leave it
empty to use the entire field.
Note that a REX Search must be specified for the following
From field types:
You can specify they entire field for these by using .* as the
REX Search.
Replace - Replace can be used to specify a subset of the
value to be stored in the To field (or subset of the match, if
you're using REX Search. It uses sandr replacement
string syntax.
From Field - specifies what the source field is for the data.
-
HTML - the raw HTML source of the page. -
Text - the text of the page, after HTML rendering has
been applied. -
Title - the HTML title of the page -
All Meta - the contents of all meta headers
specified in the HTML page. -
Meta Field-> - the contents of a specific meta
field, specified in the next input box, From Meta Field. -
Keywords - the contents of the keywords meta
header. -
Description - the contents of the description meta
header. -
Mime Type the MIME type of the page. This may have been
derived from the Content-Type header, a
<META HTTP-EQUIV> tag, or the URL extension, depending on
what is available. -
URL - the URL of the page. -
URL Decoded - the decoded version of the URL. Any %XX
'URL-safe' sequences in the URL are replaced with their real
characters. Pre%20%2D%20Expense%20Report.doc is decoded into
Pre - Expense Report.doc.
From Meta Field - If you're using Meta Field-> as your
source, this field is used to specify which meta field's contents you
want to use as your source. If you're not using Meta Field->,
leave this field blank.
Entering text in this field will force the use of Meta Field->,
regardless of From Field's settings.
To Field - specifies where information should be stored.
Modified Date, Title, and `verb`Description` are the
standard HTML fields. If you've defined any Additional Fields,
they will also be listed as selections here.
