Question

XPATH get value of attribute when attribute of same node equals specified value

Asked by: websuperman

I need to be able to select data that is located in an attribute in an element where another attribute matches a given value.   For instance, in the following sample xml I would like to get the value contained in Employee_ID where Emp_ID is W2635#FL .  I sometimes may need to get both the value fo Employee_ID AND path for a given element where the specified attribute has the specified value.  

<ROOT>
	<INDEX Created="20090815">
		<file path="home/usr18/reports.xml" Employee_ID="2475" Employer_id="8" Emp_ID="W2475#KY" Employee_Name="Jack Smith" />
		<file path="home/usr25/reports.xml" Employee_ID="2890" Employer_id="8" Emp_ID="W2890#KY" Employee_Name="Joe Smith" />
		<file path="home/usr16/reports.xml" Employee_ID="2635" Employer_id="6" Emp_ID="W2635#FL" Employee_Name="Jane Smith" />
		<file path="home/usr13/reports.xml" Employee_ID="1862" Employer_id="242" Emp_ID="W1862#GA" Employee_Name="Jorge Smith" />
	</INDEX>
</ROOT>

A simple predicate will do

/ROOT/INDEX/file[@Emp_ID = 'W2635#FL' ]/@Employee_ID

 

by: abelPosted on 2009-08-18 at 15:29:09ID: 25128256

You can use the following XPath statements:

for the employee id:
/ROOT/INDEX/file[@Emp_ID="W2635#FL"]/@Employee_ID

for the path:
/ROOT/INDEX/file[@Emp_ID="W2635#FL"]/@path
