xpath

问题 Good day everyone. I'm working on a very simple application and I want to implement something that will allow the user to choose a tool from a drop down menu, and after clicking the submit button it will show the information of the chosen tool by extracting the information from the XML File. I created the dropdown menu by extracting the tool names from the XML file: <form method="POST" action="showspecifictool.php"> <select id="choose" name="choose"> <?php $tools = simplexml_load_file('tools

I know that a leaf node is a node without any children, but it also seems that the atomic nodes in the given example don't have any children either. The W3Schools site says "Atomic values are nodes with no children or parent." Surely it's impossible for

问题 Here is a sample XML, and I am trying to figure out how to select first node value and exit the loop. If I use following XSLT tag <xsl:value-of select="fruits/fruit"/> it returns "apple mango banana" but expected result should be "apple" <fruits> <fruit>apple</fruit> <fruit>mango</fruit> <fruit>banana</fruit> </fruits> I'd also like to select the last fruit without knowing how many fruit exist a priori. So, for the above example, I'd like to return "banana" without knowing that there are 3

问题 I have a Google Sheet where rows are products and columns are information about these products (Material, Color, Price, ...). These information are retrieved using the function IMPORTXML with the corresponding xpath query. In the following example, the column D is the URL of this product. These functions retrieve information (Glass, Color and Type) for the product on row 3: =IMPORTXML(D3,"//table[@class='info-table']/tr[th/text()[contains(.,'Glass')]]/td") =IMPORTXML(D3,"//table[@class='info
