Am trying to read content of PDF using XPATH. Below mentioned is the PDF's tree structure. I could access till "<div id="viewer" class="pdfViewer">"

but could not access "<div class="page" "

Any suggestions will help

PDF Stucture:

</head>

.......

</div>

</div>

XPATH

String path1 = "/html/body/div[@id='outerContainer']/div[@id='mainContainer']/div[@id='viewerContainer']/div[@id='viewer']/div[@class='.page']";

Error Message:

[Child 9404, Chrome_ChildThread] WARNING: pipe error: 109: file z:/build/build/srException in thread "main" org.openqa.selenium.NoSuchElementException: Unable to locate element: /html/body/div[@id='outerContainer']/div[@id='mainContainer']/div[@id='viewerContainer']/div[@id='viewer']/div[@class='.page']

What you’re attempting to do is not possible with Selenium as far as I’m aware.

Can you provide similar UI screenshot?

One suggestion get the window midpoint if pdf point send mouse click. Then send keystrokes combinations ctrl+A, then send keystrokes combinations ctrl+c.

You will have the pdf content in your clipboard.

Now you can do string manipulation to get the desired stuff.

Hope it helps...:)

Yeah, you won't be able to inspect anything on a PDF directly with any UI automation tool.

Alternatively, you can use automation to download the documents and you can convert and parse the contents with something like PDFBox.

Once again: Selenium is unable to do what you are trying to use it for. The Workfusion URL you posted is nothing to do with Selenium.

It won't work.

You have typo in xpath, extra dot in '.page'.
