Subject: [xsl] What is the most efficient XPath expression for retrieving the first child element? From: "Costello, Roger L. costello@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx> Date: Sun, 12 May 2019 11:43:32 -0000 |
Hello XSLT experts! I want to retrieve the first child element. The children consist of a <Total_Size> element followed by many <String> elements (perhaps thousands of <String> elements). <COFF_String_Table> <Total_Size>4443</Total_Size> <String>.eh_frame</String> <String>.debug_aranges</String> <String>.debug_info</String> ... </COFF_String_Table> Question: What is the most efficient XPath for selecting the first child element (the <Total_Size> element)? Assume the context node is the <COFF_String_Table> element. Which of these is the most efficient XPath expression: (a) child::*[1] (b) child::Total_Size (c) something else (what?) /Roger
