xml learning (7) .net obtains the maximum value of xml node or attribute
xml learning (7) .net obtains the maximum value of xml node or attribute
上一节中，我们介绍了一些xml的xpath属性和函数
下面我们来介绍两个比较特殊的使用：
1.获取相同节点的最大值
2.获取相同节点某属性最大值
xmlName为“内容”
1.获取相同节点的最大值
string fileName = HttpContext.Current.Request.PhysicalApplicationPath + "\\Xml\\" + xmlName + ".xml";//xml的物理路径
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(fileName);
XmlNode fdfdf = xmlDoc.SelectSingleNode("//rows[not(.<//rows)]");2.获取相同节点某属性最大值
string fileName = HttpContext.Current.Request.PhysicalApplicationPath + "\\Xml\\" + xmlName + ".xml";//xml的物理路径
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(fileName);
XmlNode maxNodejj = xmlDoc.SelectSingleNode("//rows/@ID[not(.<//rows/@ID)]");
下面是内容.xml
<?xml version="1.0" encoding="utf-8"?> <config> <Header ID="ID" class="class" class_name="class_name" year="year" school="school" count="count">2 </Header> <rows ID="01" class="一五班" class_name="实验班" year="2013" school="三峡高级中学" count="30">4 </rows> <rows ID="02" class="一六班" class_name="奥数班" year="2013" school="三峡高级中学" count="25">9 </rows> <rows ID="03" class="一七班" class_name="阳光班" year="2013" school="三峡高级中学" count="69">8 </rows> </config>
