Considering this code example and this post
...
<xf:action>
<xf:setvalue
iterate="instance('fr-send-submission-params')/#*"
ref="."
value="event(name(context()))"/>
</xf:action>
...
How can refer to current iterated position? Like value="position()"
Can i use this position as variable to xpath expressions? Like ref="/AnotherElement[position()]"
The following works:
<xf:action iterate="instance('fr-send-submission-params')/#*">
<xf:var name="p" value="position()"/>
<xf:setvalue ref="." value="$p"/>
</xf:action>
I don't think you can get away just with xf:setvalue, because ref changes the evaluation context of the expression to a single item which means that position() returns 1 within value.
A warning as I see that you iterate on attributes: I don't think that attribute position is guaranteed to be consistent.
Update:
The following works if you have elements, but then you need to have knowledge of the items iterated within the xf:setvalue:
<xf:setvalue
event="DOMActivate"
iterate="value"
ref="."
value="count(preceding-sibling::value) + 1"/>
So I think that the option with an enclosing action is much clearer.

For example I have an XML element:
<input id="optSmsCode" type="tel" name="otp" placeholder="SMS-code">
Suppose I know that somewhere there must be an attribute with otp value, but I don’t know in what attribute it can be, respectively, is it possible to have an XPath expression of type like this:
.//input[(contains(*, "otp")) or (contains(*, "ode"))]
Try it like this and see if it works:
one = '//input/#*[(contains(.,"otp") or contains(.,"ode"))]/..'
print(driver.find_elements_by_xpath(one))
Edit:
The contains() function has a required cardinality of first argument of either one or zero. In plain(ish) English, it means you can check only one element at a time to see if it contains the target string.
So, the expression above goes through each attribute of input separately (/#*), checks if the attribute value of that specific attribute contains within it the target string and - if target is found - goes up to the parent of that attribute (/..) which, in the case of an attribute, is the node itself (input).
This XPath expression selects all <input> elements that have some attribute, whose string value contains "otp" or "ode". Notice that there is no need to "go up to the parent ..."
//input[#*[contains(., 'otp') or contains(., 'ode')]]
If we know that "otp" or "ode" must be the whole value of the attribute (not just a substring of the value), then this expression is stricter and more efficient to evaluate:
//input[#*[. ='otp' or . = 'ode']]
In this latter case ("otp" or "ode" are the whole value of the attribute), if we have to compare against many values then an XPath expression of the above form will quickly become too long. There is a way to simplify such long expression and do just a single comparison:
//input[#*[contains('|s1|s2|s3|s4|s5|', concat('|', ., '|'))]]
The above expression selects all input elements in the document, that have at least one attribute whose value is one of the strings "s1", "s2", "s3", "s4" or "s5".
I am using an XForms action along with iterate. The iterate selects a set (using XPath) of nodes and repeats the action for it.The problem is I have multiple conditions for selecting the node set.
There should not be a readOnly node.
Should not be part of the ignoreProperties list (this list is in another instance).
Code:
<xf:action ev:event="setValues" iterate="
instance('allProps')/props/prop[
not(readOnly) and
not(instance('ignoreProperties')/ignoredProperties/property[text() = name]
]
">
The first condition not(readOnly) works. But the second condition does not work. I feel there is some problem with the context of the XPath nodes.
How should I replace the second condition to achieve the result ?
The target XML is a simple ignoredProperties document:
<ignoredProperties>
<property>c_name</property>
<property>c_tel_no</property>
</ignoredProperties>
This should work:
<xf:action ev:event="setValues" iterate="
instance('allProps')/props/prop[
not(readOnly) and
not(name = instance('ignoreProperties')/ignoredProperties/property)
]
">
The = operator works against multiple nodes, returning all the ones that match. With not() you can express that you don't want a match.
Explicitly selecting .../property/text() will not be necessary.
There seems to be something wrong with your calls to instance(). If you have:
<xf:instance id="ignoredProperties">
<ignoredProperties>
<property>c_name</property>
<property>c_tel_no</property>
</ignoredProperties>
</xf:instance>
Then instance('ignoredProperties') returns the <ignoredProperties> element. So you should write:
<xf:action ev:event="setValues" iterate="
instance('allProps')/prop[
not(readOnly) and
not(instance('ignoreProperties')/property[text() = name])
]
">
This also assumes your allProps instance has a <props> root element.
Further, the second condition appears wrong, as already shown in another answer. Write instead:
not(name = instance('ignoreProperties')/property)
In XPath 2, you could clarify that your not() are testing on node existence by using empty() instead:
<xf:action ev:event="setValues" iterate="
instance('allProps')/prop[
empty(readOnly) and
not(name = instance('ignoreProperties')/property)
]
">
Considering theses xpath expressions :
//*[#id="searchResults"]/div[1]/div[1]/h2/span
//*[#id="searchResults"]/div[3]/div[1]/h2/span
//*[#id="searchResults"]/div[5]/div[1]/h2/span
For your info the div inside search result's class is article searchResult and the one inside article searchResult is header.
I am not sure how to construct an xpath matching all three of the above elements. Is there a tool or a how to guide for that?
Thanks
Use position function
//*[#id="searchResults"]/div[position()=1 or position()=3 or position()=5]/div[1]/h2/span
If, by 'all', you mean all div in even position index, then you can use mod operator to check :
//*[#id="searchResults"]/div[position() mod 2 = 1]/div[1]/h2/span
but if 'all' literally means all, then you don't need index to return all matched elements :
//*[#id="searchResults"]/div/div[1]/h2/span
I am trying to click an element that changes per each order like so
edit_div_123
edit_div_124
edit_div_xxx
xxx = any three numbers
I have tried using regex like so:
#driver.find_element(:css, "#edit_order_#{\d*} > div.submit > button[name=\"commit\"]").click
#driver.find_element(:xpath, "//*[(#id = "edit_order_#{\d*}")]//button").click
Is this possible? Any other ways of doing this?
You cannot use Regexp, like the other answers have indicated.
Instead, you can use a nifty CSS Selector trick:
#driver.find_element(:css, "[id^=\"edit_order_\"] > div.submit > button[name=\"commit\"]").click
Using:
^= indicates to find the element with the value beginning with your criteria.
*= says the criteria should be found anywhere within the element's value
$= indicates to find the element with with your criteria at the end of the value.
~= allows you to find the element based on a single criteria when the actual value has multiple space-seperated list of values.
Take a look at http://net.tutsplus.com/tutorials/html-css-techniques/the-30-css-selectors-you-must-memorize/ for some more info on other neat CSS tricks you should add to your utility belt!
You have no provided any html fragment that you are working on. Hence my answer is just based on the limited inputs provided your question.
I don't think WebDriver APIs support regex for locating elements. However, you can achieve what you want using just plain XPath as follows:
//*[starts-with(#id, 'edit_div_')]//button
Explanation: Above xpath will try to search all <button> nodes present under all elements whose id attribute starts with string edit_div_
In short, you can use starts-with() xpath function in order to match element with id format as edit_div_ followed by any number of characters
No, you can not.
But you should do something like this:
function hasClass(element, className) {
var re = new RegExp('(?:^|\\s+)' + className + '(?:\\s+|$)');
return re.test(element.className);
}
This worked for me
#driver.find_element(:xpath, "//a[contains(#href, 'person')]").click

I would like to make a xpath query that takes both index and attribute into account.
I.e can I combine these two into ONE query? (Its the stuff around the "object" element Im interested in):
//techMD/mdWrap[
#MDTYPE=\'PREMIS:OBJECT\'
]/xmlData//object[1]/objectIdentifier/objectIdentifierValue
//techMD/mdWrap[
#MDTYPE=\'PREMIS:OBJECT\'
]/xmlData//object[
#xsi:type=\'premis:file\'
]/objectIdentifier/objectIdentifierValue
Thanks!
Just replace according part to:
object[#xsi:type='premis:file'][1]
if you want first object of those who have a given xsi:type value or
object[1][#xsi:type='premis:file']
if you want the first object, providing it has a given xsi:type value.
