get xml query result
Description
Query an XML string by XPath.
Arguments
xml
XML target string that the query runs against.
ヒント:To access content from an XML file, use the get text file action to load the XML document into a variable, then reference the variable in this argument.xpath
XPath query string.
variable
(Optional) Variable to receive the returned query result.
Notes
- It is possible to insert an entire XML file’s content into the xml argument; however, all whitespace and line breaks between XML nodes must be removed manually to avoid automation failure (see example #4 below).
- Depending upon the XPath query, some of the following notes for the variable argument may apply:
- The returned value may contain multiple XML nodes. To extract or check the content of a single line from variable, use the get text line or check text line actions. (See example #5.)
- If the returned value contains multiple XML nodes, and is to be used in another XPath query, ensure that it is well-formed XML by adding a single root element at the top level (see example #6).
- If the variable in argumentvariablehas not been declared, the action creates it as a global.
- If the variable argument is left empty, TestArchitect supplies a global variable with the name _result.
- If your XML target string has a namespace (defined by the xmlns attribute in the start tag of an element), yet no namespace is configured in the XPath expression, your query strings will not return any result. To resolve this namespace problem, you may use the local-name() function. This function returns the query results as if no namespace is declared in the target string (see example #7 below).
- This action supports the <ignore> modifier. If the string
<ignore>is present as the value of any of the arguments, or any argument contains an expression that evaluates to<ignore>, the action is skipped during execution.

Example - Case 1: Using an XPath predicate in an XPath query
The following example retrieves the text from the title element of the first book element that is a child of a bookstore element.
<?xml version="1.0"?>
<bookstore>
<book id="bk101" category="COOKING">
<title lang="en">Everyday Italian</title>
<author>Giada De Laurentiis</author>

<book id="bk102" category="CHILDREN">

Example - Case 3: Using a data set
The following example repetitively retrieves the text from the price element based on the title variable defined within a data set.
As an example, the first iteration of the use data set loop issues an XPath query of //price[../title="Everyday Italian"]/text().

Example - Case 4: Passing an entire XML file’s content into the xml argument
The following example passes an entire well-formed XML string into the xml argument. Whitespace and line breaks between XML nodes within the document have been removed beforehand, as required.

Example - Case 5: Using get text line to extract content
The following example extracts a single XML line, <title lang=“en”>Harry Potter</title>, from a variable holding multiple XML lines by using the get text line action.

Example - Case 6: Adding a single root element
The following example encloses the returned XML document in a single root element to ensure a well-formed XML document. The modified XML document is then used to calculate the sum of all price nodes.

Example - Case 7: Resolving the problem of namespaces
Let’s see an example of an XML file with a namespace:
<cr:cricketers xmlns:cr="http://www.example.com/">
<cr:cricketer type="righty">
<name>MS Dhoni</name>
<role>Captain</role>
<position>Wicket-Keeper</position>
</cr:cricketer>
</cr:cricketers>
Use the local-name() function for your XPath, in order to retrieve the content of the <name> element of the cricketer node despite its enclosure in a namespace. For example, //*[local-name()=‘cricketer’]/name/text():
