XPath Assertions

Hello, I have the following response from a very simple WebService

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <soap:Body>
      <GetRandomResponse xmlns="http://seant/webservices/">
         <GetRandomResult>15</GetRandomResult>
      </GetRandomResponse>
   </soap:Body>
</soap:Envelope>


I am asserting that the value in the <GetRandomResult> tag is numeric with the following XPath assertion (its working just fine)


declare namespace soap='http://schemas.xmlsoap.org/soap/envelope/';
declare namespace ns1='http://seant/webservices/';
matches(/soap:Envelope/soap:Body/*[namespace-uri()='http://seant/webservices/' and local-name()='GetRandomResponse']/*[namespace-uri()='http://seant/webservices/' and local-name()='GetRandomResult']/text(),'^\d{1,2}$')


This is quite a bit of typing so I would like to use this instead
matches(//GetRandomResult/text(),'^\d{1,2}$')
but it keeps failing and I am not sure why. I have validated this expression in other editors and its fine, just not sure what is going on.

Any thoughts would be appreciated
Sean

    May be the count is changing and the pattern is not matching along with namespace missing, a wild guess?

    Would you mind trying with pattern ^\d+$ instead of current one?

    matches(//ns1:GetRandomResult/text(),'^\d+$')


    Hoping the expected value is true

    Hi there, many thanks for the response.
    What you posted works just fine.

    I am not really up on the whole namespace thing so its not clear to me what the ns1 in your expression actually means / does?
    matches(//ns1:GetRandomResult/text(),'^\d+$')

    Actually, nevermind, just had a look at the declared namespace in the wizard..

    declare namespace soap='http://schemas.xmlsoap.org/soap/envelope/';
    declare namespace ns1='http://seant/webservices/';
    matches(//ns1:GetRandomResult/text(),'^\d{1,2}$')I think I get it now.

    Sorry.

    ^\d{1,2}$ - works for two digit numbers only, where as ^\d+$ works for any number of digits but there should be minimum 1 integer.

    Hi,

    Is it possible to retrieve more than 1 data in REST service using X-Path assertion? .

    My XML is -
    <ul id="subjects">
    <li>
    <a class="uri" href="/OvidWS/journals/adisovft/subjects/Arts+%26+Humanities">
    <span class="name">Arts &amp; Humanities</span>
    </a>
    ; # Journals:
    <span class="num_journals">1</span>
    </li>
    <li>
    <a class="uri" href="/OvidWS/journals/adisovft/subjects/Arts+%26+Humanities%3ABusiness+%26+Economics">
    <span class="name">Arts &amp; Humanities:Business &amp; Economics</span>
    </a>

    It contains more than 100 names which i want to retrieve using X-Path. Is it possble?? Please reply.

    Retrieving one or many values should not be problem if you use right xpath. Are you facing any issue currently?
