The code is as follows: /* */ if (!function_exists (' l ')) { function L () { echo ' } } if (file_exists (' Test10_12.xml ')) { $xml = simplexml_load_file (' Test10_12.xml '); Finding node locations using the XPath method $query = $xml->

The core idea of XPath design can be quickly introduced by xpath to locate the desired node. The main purpose is to describe the location of a node relative to another node. All qualified nodes can be obtained and become [location paths]. Xapth is mainly used to query information in XML documents. You can use path expressions to parse

Copy Code code as follows: /* */ if (!function_exists (' l ')) { function L () { echo ' } } if (file_exists (' Test10_12.xml ')) { $xml = simplexml_load_file (' Test10_12.xml '); Finding node locations with XPath methods $query = $xml->

= "/*"; node = (Node) xpath.evaluate(expression, doc, XPathConstants.NODE); System.out.println("1. " + node.getNodeName()); // 2. root element (by name) expression = "/rss"; node = (Node) xpath.evaluate(expression, doc, XPathConstants.NODE); System.out.println("2.

Document directory Processing node Nodes functions Returns a Boolean function. Function for processing string Strings Function for processing numeric Numbers Location path: path, which is equivalent to the path of a file in the file system. XML documents contain many elements and attributes. The Location of nodes, elements, and attributes specified according to the XPath syntax rules in the

Today, with the help of the instance for configuring Oracle database connection, we will learn one way to read xml files (other reading methods will be introduced later)-using dom4j + xpath. Dom4j is an open-source XML parsing package produced by dom4j.org. Therefore, the package "dom4j-1.6.1.jar" must be copied to the web-inf/lib. We take the

Copy codeThe Code is as follows:/**/If (! Function_exists ('l ')){Function l (){Echo '}}If (file_exists ('test10 _ 12. xml ')){$ Xml = simplexml_load_file ('test10 _ 12. xml ');// Use the xpath method to find the node location$ Query = $ xml->

Through XPath, we can quickly find the desired node, such: Use the following code to search for the URL node xmlnodelist urlnodes = Doc. selectnodes ("/urlset/url "); However, if you change the XML: When xmlnodelist urlnodes = Doc. selectnodes ("/urlset/url") is used, an empty list is returned, that is, the URL node cannot be searched. You can use xmlnamespacemanager to solve this problem: XmlNamespac
