The Find/Replace Dialog Box

To open the Find/Replace dialog box, use the Find/Replace... action that is available in the Find menu, on the toolbar, or by pressing Ctrl F (Command F on OS X).

You can use the Find/Replace dialog box to perform the following operations:

Replace occurrences of target defined in the Find area with a new fragment of text defined in Replace with area.
Find all the occurrences of a word or string of characters (that can span over multiple lines) in the document you are editing. This operation also takes into account all the white spaces contained in the fragment you are searching for.

Note: The Find/Replace dialog counts the number of occurrences of the text you are searching for and displays it at the bottom of the dialog, above the Close button. This number is also displayed in the Results view.

The find operation works on multiple lines, meaning that a find match can cover characters on more than one line of text. To input multiple-line text in the Find and Replace with areas, do one of the following:

Press Ctrl Enter (Command Enter on OS X) on your keyboard.
Use the Insert newline contextual menu action.

You can use Perl-like regular expressions syntax to define patterns. A content completion assistant window is available in the Find and Replace with areas to help you edit regular expressions. It is activated every time you type \(backslash key) or on-demand if you press Ctrl Space (Command Space on OS X) on your keyboard.

The replace operation can bind regular expression capturing groups ($1, $2, etc.) from the find pattern.

To replace the tag-name start tag and its attributes with the new-tag-name tag use as Find the expression <tag-name(\s+)(.*)> and as Replace with the expression <new-tag-name$1$2>.

The dialog box contains the following options:

Find - The target character string to search for. You can search for Unicode characters specified in the \uNNNN format. Also, hexadecimal notation (\xNNNN) and octal notation (\0NNNN) can be used. In this case you have to select the Regular expression option. For example, to search for a space character you can use the \u0020 code.
Replace with - The character string with which to replace the target. The string for replace can be on a line or on multiple lines. It can contain Perl notation capturing groups, only if the search expression is a regular expression and the Regular expression option is selected.
Note: Some regular expressions can block indefinitely the application. If the execution of the regular expression does not end in about 5 seconds, the application displays a dialog that allows you to interrupt the operation.

Note: Special characters like newline and tab can be inserted in the Find and Replace with text boxes using dedicated actions in the contextual menu (Insert newline and Insert tab).
Unicode characters in the \uNNNN format can also be used in the Replace with area.
The History button - Contain lists of the last find and replace expressions. Use the Clear history action from the bottom of the lists to remove these expressions.
XPath - The XPath 2.0 expression you input in this combo is used for restricting the search scope.
Note: The Content Completion Assistant helps you input XPath expressions, valid in the current context.
Direction - Specifies if the search direction is from current position to end of file (Forward) or to start of file (Backward).
Scope - Specifies whether the Find/Replace operation is executed over the entire content of the edited document (All option), or over the selected lines of text (Only selected lines option). In case the selection spans across multiple lines, when you open the Find/Replace dialog box, the scope is set to Only selected lines.
Case sensitive - When checked, the search operation follows the exact letter case of the Find.
Whole words only - Only entire occurrences of a word are included in the search operation.
Incremental - The search operation is started every time you type or delete a letter in the Find text box.
Regular expression - When this option is enabled, you can use regular expressions in Perl-like regular expressions syntax to look for specific pieces of text.
- Dot matches all - A dot used in a regular expression also matches end of line characters.
- Canonical equivalence - If enabled, two characters will be considered a match if, and only if, their full canonical decompositions match. For example, the ã symbol can be inserted as a single character or as two characters (the a character, followed by the tilde character). This option is disabled by default.
Wrap around - When the end of the document is reached, the search operation is continued from the start of the document, until its entire content is covered.
Enable XML search options - This option is only available when editing in Text mode. It provides access to a set of options that allow you to search specific XML component types:
- Element names - Only the element names are included in the search operation which ignores XML-tag notations ('<', '/', '>'), attributes or white-spaces.
- Element contents - Search in the text content of XML elements.
- Attribute names - Only the attribute names are included in the search operation, without the leading or trailing white-spaces.
- Attribute values - Only the attribute values are included in the search operation, without single quotes(') or double quotes(").
- Comments - Only the content of comments is included in the search operation, excluding the XML comment delimiters ('').
- PIs (Processing Instructions) - Only the content are searched, skipping '<?', '?>'. e. g.: <?processing instruction?>
- CDATA - Searches inside content of CDATA sections.
- DOCTYPE - Searches inside content of DOCTYPE sections.
- Entities - Only the entity names are searched.
The two buttons Select All and Deselect All allow a simple activation and deactivation of all types of XML components.

Note: Even if you enable all options of the Enable XML search options section, the search is still XML-aware. If you want to perform the search over the entire file content, disable Enable XML search options.
Find All Elements... - Available when editing in Author mode, you can use this link to extend the search scope to XML-specific markup (names and values of both attributes and elements).
Find - Executes a find operation for the next occurrence of the target. It stops after highlighting the find match in the editor panel.
Replace - Executes a replace operation for the target followed by a find operation for the next occurrence.
Find All - Executes a find operation and displays all results in the Results view. The results are displayed in the Results view.
Replace All - Executes a replace operation in the entire scope of the document.
Replace to End - Executes a replace operation starting from current target until the end of the document, in the direction specified by the current selection of the Direction switch (Forward or Backward).
