child::node(): 选择当前节点的所有子节点。 parent::node(): 选择当前节点的父节点。 following-sibling::node(): 选择当前节点之后的所有同级兄弟节点。 XPath 轴提供了灵活的导航和选择机制,使我们能够精确地定位和操作文档中的元素。 二、示例用法 1、子节点轴 //div[@id="s-top-left"]/child::a获取...
//div[@id="u"]/child::node(),先找到一个id属性为u的div,再找到这个div的所有孩子节点,后面跟[1],就是这些孩子节点的第一个节点。 每天进步一点点~
// Display the LocalName of each child node.Console.WriteLine("\nChild nodes of the book node:");while(bookChildren.MoveNext()) { Console.WriteLine(bookChildren.Current.Name); }// Select all the ancestor nodes of the title node.navigator.MoveToChild("title","http://www.contoso.com/...
On each child node you reach from XmlDocument, a couple of search methods are implemented. The XmlNode class provides the SelectNodes and SelectSingleNode methods that use XPath expressions to search for nodes in the document. The methods are nearly identical to similarly named methods in the COM...
Console.WriteLine("\nChild nodes of the book node:"); while (bookChildren.MoveNext()) { Console.WriteLine(bookChildren.Current.Name); } // Select all the ancestor nodes of the title node. navigator.MoveToChild("title", "http://www.contoso.com/books"); XPathNodeIterator bookAncestors = na...
一、选取节点 常用的路劲表达式: 二、谓语 谓语被嵌在方括号内,用来查找某个特定的节点或包含某个制定的值的节点 实例: 三、通配符 Xpath通过通配符来选取未知的XML元素 四、取多个路径 使用“|”运算符可以选取多个路径 五、Xpath轴 轴可以定义相对于当前节点的节点集 ...
child named Z with value '10'. :) X[Z eq '10'] (: Select X children that have a child named Z with value not equal to '10'. :) X[Z ne '10'] (: Select X children if they have at least one child text node. :) X[text()] (: Select X children if they have a text ...
returns a node-set consisting of up to three element nodes. If no element nodes match a particular value, no error condition exists. In this example, if no element node has an ID-type attribute whose value is sect_05 but there are matches for the other two values, the resulting node-se...
Select the Set as child check box to set the element as a child of the structure being created. Click Add to create the variable structure. Create a variable structure that uses an MFL resource At the top of the Variable Structures palette, select XML Type, if it is not already selected...
