Using XPATH to isolate inline javascript - Stack Overflow

I'm trying to extract inline javascript that is uniquely different on thousands of URLs, and is nested within the code at various levels.

As I familiarize myself with XPATH syntax I am trying to see if anyone knows a good way to target javascript For example:

<script type="text/javascript"> ...data_#...</script>
<script type="text/javascript"> ...data_#...</script>
<script type="text/javascript"> ...data_n...</script>
<script type="text/javascript"> ...data_#...</script>
<script type="text/javascript"> ...data_#...</script>

The only unique identfier within the <script>...data_n...</script> that I am attempting to extract is it contains:

var tabsRelated = ...

Within the confines of XPATH does anyone know a way to find the script that contains that variable and target the entire script? Sorta like:

//script[inner.text contains='var tabsRelated'

syntax is not proper

• The question I am asking refers to a more plex problem. In the cited discussion text() seems only to apply to HTML elements. I am unable to use this to isolate the above mentioned inline javascript. – user856197 Commented Nov 7, 2011 at 20:09
• 1 XPath has no concept of javascript. It's just plain text as far as string searching is concerned. Find JS nodes, and check if their textvalue contains the string you want. – Marc B Commented Nov 7, 2011 at 20:10

Use:

//script[contains(., $someDistinguishingValue)]

where $someDistinguishingValue should be replaced with the corresponding value (for example the above XPath expression may be dynamically generated as a string and then this string evaluated as an XPath expression using the available XPath API (such as the DOM method SelectNodes() ).
