Finding only required links on a webpage using xpath - xpath

Question

I have a webpage that has more than hundred links on a webpage. I am trying to see if i can only store the required number of web links and store them in a array and run a loop for verifying data within each individual links.
The number of links are dynamic and change as per the user, so each time the page loads it has to find the specified links.
This is what i currently have under the for loop for each user:
List<WebElement> linksize = driver.findElements(By.xpath(obj.getProperty("totalbookings")));
int linksCount = linksize.size();
String[] linksENR = null;
linksENR = new String[linksCount];
System.out.println(linksCount);
if (linksCount > 0)
{
System.out.println("We have enrollment");
System.out.println(linksCount);
for (int i = 1; i <= linksCount; i++)
{
driver.navigate().to(linksENR[i]);
System.out.println("here");
}
}
else
{
System.out.println("No enrollment record found");
}
The xpath for the elements that i am trying to click for user 1 is and there is one element:
.//*[#id='006g0000007RH1V_00Nb0000009Yc1K_body']/table/tbody/tr[2]/th/a
The xpath for the elements that i am trying to click for user 2 is as follows and there are two elements:
.//*[#id='006g0000007RH1V_00Nb0000009Yc1K_body']/table/tbody/tr[2]/th/a
.//*[#id='006g0000007RH1V_00Nb0000009Yc1K_body']/table/tbody/tr[3]/th/a
This is what i am using to search with the xpath:
totalbookings = .//*[contains(#id, "7RH1V_00Nb0000009Yc1K_body") and contains(#tagName , "a")]
Output:
No enrollment record found
Is there way to uniquely identify only few chosen links with the xpath? Please assist.
Here is the HTML information for the element:
<table class="list" cellspacing="0" cellpadding="0" border="0">
<tbody>
<tr class="headerRow"></tr>
<!--
ListRow
-->
<tr class="dataRow even first" onmouseover="if (window.hiOn){hiOn(this);}" onmouseout="if (window.hiOff){hiOff(this);}" onfocus="if (window.hiOn){hiOn(this);}" onblur="if (window.hiOff){hiOff(this);}">
<td class="actionColumn"></td>
<th class=" dataCell " scope="row">
<a class=" firepath-matching-node" href="/a1Bg0000001ih6M"></a>
</th>
<td class=" dataCell CurrencyElement"></td>
<td class=" dataCell "></td>
<td class=" dataCell "></td>
<td class=" dataCell "></td>
<td class=" dataCell numericalColumn"></td>
<td class=" dataCell "></td>
</tr>
<!--
ListRow
-->
<tr class="dataRow odd last" onmouseover="if (window.hiOn){hiOn(this);}" onmouseout="if (window.hiOff){hiOff(this);}" onfocus="if (window.hiOn){hiOn(this);}" onblur="if (window.hiOff){hiOff(this);}"></tr>
</tbody>
</table>

Answer 1

I would do it more like this:
List<WebElement> pl = driver.findElements(By.xpath(".//a[contains(#id,'totalbookings')]"));
if (pl.size() > 0)
{
System.out.println("We have enrollment. Looping through links...");
for ( WebElement we : pl )
{
we.click();
System.out.println("Clicked link: " + we.toString() );
thisPageObject.verifyPageLoaded();
driver.executeScript("window.history.go(-1)");
org.openqa.selenium.browserlaunchers.Sleeper.sleepTight(1000);
}
} else {}
System.out.println("No enrollment record found");
}

Answer 2

I guess contains(#tagName , "a") is intended to mean that the current element has a descendent element a. But it actually means that the current element has an attribute named tagName, and this attribute's string value contains the letter "a".
This says to me that you are trying to do something moderately complex with a tool that you really know little about. There's no shame in not knowing XPath, but a few hours spent learning the fundamentals will spare you many hours of trial and error and trying to communicate your problem on web forums.
To do what I think you intended to do, you can use the following XPath expression:
.//*[contains(#id, "7RH1V_00Nb0000009Yc1K_body")]//a
That is if you're trying to select the links themselves. If you're trying to select the element whose id you're testing, as your totalbookings XPath expression implies, you could do
.//*[contains(#id, "7RH1V_00Nb0000009Yc1K_body") and .//a]
but that would not select the links, which was your stated goal.
Also, both of the above look for descendants of the current element (whatever that is). With driver.findElements() you don't seem to have a current node, so it would make more sense to remove the . from the beginning of the XPath and just use //*... to make it clear that you're looking for nodes anywhere in the web page, not just in some chosen subtree.
