Example. Finding and replacing a string using regular expression.
Consider the following XML code fragment:
<new product="ij" category="105" title="Multiline search and replace in the current file" /> <new product="ij" category="105" title="Improved search and replace in the current file" /> <new product="ij" category="105" title="Regexp shows replacement preview" /> ...
Suppose you want to replace an attribute within an element (title) with an expanded tag <title></title>, which contains some arbitrary string in double-quotes within.
This is how it's done.
- With the XML file in question opened in the editor, press Ctrl+RCtrl+RCtrl+RCtrl+RShift+Alt+5Ctrl+HCtrl+HCtrl+FCommand RCommand RCommand R. The Replace pane appears on top of the editor.
- Since you want to replace all the title attributes, regardless of the actual strings contained therein, use regular expressions. Make sure that the check box Regex is selected. Thus everything you type in the Search and Replace fields will be perceived as the regular expressions.
- In the Search field, start typing regular expression that describes all title attributes.
Note that though the regular expression \stitle=".*?"\s*[/>]* matches
contents of the title
attribute, it is recommended to capture the groups for referencing them in the Replace field:
Note that for the regular expressions replacement preview is shown at the tooltip.
- Then, in the Replace field, type the following regular expression:
- Click Replace, or Replace All.
As you see, the second capture group (/>) is moved ahead to close the <new> element, while the first capture group <, which matches any string in double quotes, is moved to the element <title>.
