EvaluateXPath Method (Web Objects)

Applies to TestComplete 15.63, last modified on April 10, 2024


Use the EvaluateXPath method to find an element on a web page by the values of the element’s attributes. The search condition is specified using the XPath syntax. TestComplete first searches the child objects and if nothing is found, continues the search at deeper levels of the object hierarchy (in XPath terms, it searches through the descendants of the specified node).

The method returns an array of the matched elements. To search for a single element, use the FindChildByXPath method.

The function searches by the names of HTML elements and attributes. It does not use object names that are displayed in the Object Browser panel.

The function finds only web page elements. It does not find and return internal objects of Flash or Silverlight applications embedded into the tested web page.

The function does not find objects in WebView nested frames.

Note that the function uses the element’s attributes, not properties. The attributes can be specified in the HTML code, or they can be added to the element by the setAttribute script function. See the description of the setAttribute function in the MSDN Library.


TestObj.EvaluateXPath(XPath, SearchInFrames)

TestObj A variable, parameter or expression that specifies a reference to one of the objects listed in the Applies To section
XPath [in]    Required    String    
SearchInFrames [in]    Optional    Boolean Default value: True   
Result An array or null Variant value

Applies To

The method is applied to the following object:

View Mode

To view this method in the Object Browser panel and in other panels and dialogs, activate the Advanced view mode.


The method has the following parameters:


Specifies the XPath search expression.

The following requirements must be met for the specified expression:

  • The search expression must comply with the XPath rules. For more information on them, see XPath documentation. For instance, you can find XPath Reference in the MSDN Library.

  • The search expression must contain the names of HTML elements and attributes. The function does not use object names that are displayed in the Object Browser panel.

  • The element and attributes names in the search expression are case-insensitive. That is, you can specify them either in the upper case, or in the lower case.

    However, the element and attribute values, which you specify in the search expression, are case-sensitive. For instance, image1.PNG, IMAGE1.PNG and Image1.png are different values for XPath. The search expression must specify values in the same case, in which they are specified in the source code of the page. To create case-insensitive search expressions, use XPath’s translate function:

    //IMG[translate(@src, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz') = 'image1.png']

    See the documentation of XPath’s translate function in the MSDN Library for complete information about this function and its parameters.

  • In search expressions, you can use XPath 1.0 functions like contains, substring, starts-with and others.

    XPath 2.0 functions (like lower-case(), matches() and others), Microsoft extensions and other third-party extensions to XPath functions are not supported.

The table below contains some examples of XPath expressions that can be passed through the XPath parameter to search for web page elements matching the desired search criteria. Also, in the “Tips on Using XPath Expressions” section of the Finding Web Objects Using XPath Expressions topic, you can find some tips on specifying XPath expressions for the EvaluateXPath method.

Expression Description
//IMG[contains(@src, 'plusBtn.gif')] All IMG elements whose src attribute contains the plusBtn.gif substring.
//A[starts-with(@href, 'javascript:')] All A elements whose href attribute starts with the javascript: prefix.
//DIV[@class='CodeExample']/P[1] All P elements that are located at the first position within DIV elements whose class attribute is set to CodeExample.
//*[@align='center'] All web page elements that have the align attribute set to center.
//UL/* A collection of direct children of any UL element.
//UL[@id='ProductList']/LI[last()] The last LI element within the UL element that has the id attribute set to ProductList.
//DIV//A All A elements that are descendants of any DIV element.


Specifies whether the function should search within the frames' content. If it is True (default), EvaluateXPath will search within the whole object hierarchy. If it is False, the content of the frames will be excluded from the search.

Result Value

  • If the search condition matches one or several elements and the search was successful, the function returns an array of found objects.

    Tip: To search for a single element, use the FindChildByXPath method.

    If you use the EvaluateXPath method and only one element matches the search condition, the method returns an array that contains one item. If a TestComplete test object matches the found object, then the array item contains this test object. If there is no matching test object (for instance, the XPath expression returns an attribute), the array item contains the appropriate HTML object.

    Note: the returned array is Variant-compatible. It can be used as is in JavaScript, Python, VBScript and DelphiScript, but if you use JScript, C#Script or C++Script, you have to convert this array to the format supported by the JScript engine. To do this, you can use the toArray method of the variant array:

    var JScript_Array = Variant_Array.toArray()

    The use of this object is demonstrated in the Example section below.

  • If the search failed, EvaluateXPath returns a null Variant value.

  • If the search expression is a call to an XPath function, EvaluateXPath returns the result of this function.
