XPath Helper Wizard插件简介

XPath Helper Wizard插件描述

XPath Helper Wizard creates xpaths that are sht  less likely to break if the website changes. 

IMPORTANT: After installing this extension, you must reload any existing tabs  restart Chrome f the extension to wk.

If parent Xpath field contains an Xpath then all the subsequent Xpaths are generated relative to that parent Xpath. 

How to use the extension:
1. Open a new tab  navigate to any webpage.
2. Hit CtrlShiftX ( CommShiftX on OS X),  click the XPath Helper button in the toolbar, to open the XPath Helper console.
3. Hold down Shift as you mouse over elements on the page. The query box will continuously update to show the XPath query f the element below the mouse pointer,  the results box will show the results f the current query.
4. If desired, edit the XPath query directly in the console. The results box will immediately reflect your changes.
5. Repeat step (2) to close the console.

If the console gets in your way, hold down Shift  then move your mouse over it; it will move to the opposite side of the page.

One wd of caution: When rendering HTML tables, Chrome inserts artificial  tags into the DOM, which will consequently show up in queries extracted by this extension.
