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>
