我试图从XML文件中获取特定的属性值,然后将它们放入表中。
以下是XML文件的摘录:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<CUSTOMER defined="true">
<FIREWALLS defined="true">
<CMA display_name="JAPAN" ssh_port="" secondary_host_ip="" collector="Collector_A" communication="cpstat" Allow_Auto_Implementation="no" secondary_host_name="" secondary_host_sic_name="" monitoring="yes" audit_from_clm="no" log_collection_frequency="60" type="CMA" name="" host_name="" use_opsec_data_collection="yes" user_name="" passwd="" use_opsec_lea="yes" os="linux" defined="true">
<FW_CKP epasswd="" do_log_analysis="yes" defined="true" original_name="FW_A" name="FW_A" display_name="FW_A" os="sun" user_name="" passwd="" log_collection_mode="extensive" baseline_profile="" host_name="10.10.10.1" log_server="JAPAN_Pry"/>
<FW_CKP epasswd="" do_log_analysis="yes" defined="true" original_name="FW_B" name="FW_B" display_name="FW_B" os="sun" user_name="" passwd="" baseline_profile="" log_collection_mode="extensive" host_name="10.10.10.2" log_server="JAPAN_Pry"/>
<FW_CKP epasswd="" do_log_analysis="yes" defined="true" original_name="FW_C" name="FW_C" display_name="FW_C" os="sun" user_name="" passwd="" baseline_profile="" log_collection_mode="extensive" host_name="10.10.10.3" log_server="JAPAN_Pry"/>
</CMA>
<CMA display_name="USA" ssh_port="" secondary_host_ip="" collector="Collector_B" communication="cpstat" Allow_Auto_Implementation="no" secondary_host_name="" secondary_host_sic_name="" monitoring="yes" audit_from_clm="no" log_collection_frequency="60" type="CMA" name="" host_name="" use_opsec_data_collection="yes" user_name="" passwd="" use_opsec_lea="yes" os="linux" defined="true">
<FW_CKP epasswd="" do_log_analysis="yes" defined="true" original_name="FW_D" name="FW_D" display_name="FW_D" os="sun" user_name="" passwd="" baseline_profile="" log_collection_mode="extensive" host_name="10.10.10.4" log_server="USA_Pry"/>
</CMA>
</FIREWALLS>
</CUSTOMER>我需要从CMA节点获取"display_name“和”收集器“值。然后,对于每个CMA节点,我需要为每个original_name子节点获取关联的"log_server“和”FW_CKP“。最后,目的是要有一个表,其中每一行都是这样格式化的: CMA名称-收集器-原始名称-日志服务器名称。
以下是我的当前代码:
' Load XML file
doc.Load(tb_FilePath.Text)
'XML node path for CMA and FW_CKP
CMA_Nodes = doc.SelectNodes("/CUSTOMER /FIREWALLS/CMA")
FW_CKP_Nodes = doc.SelectNodes("/CUSTOMER /FIREWALLS/CMA/FW_CKP")
'loop to go through each CAM nodes
For Each CMA_Node As System.Xml.XmlElement In CMA_Nodes
'operation inside the CMA balise
CMA_Name = CMA_Node.Attributes(0).InnerText
CMA_Collector = CMA_Node.Attributes(3).InnerText
'loop to go through each FW_CKP nodes
For Each FW_CKP_Node As System.Xml.XmlElement In FW_CKP_Nodes
'Operation inside the FW_CKP baslise
Original_Name = FW_CKP_Node.Attributes(3).InnerText
Log_Server = FW_CKP_Node.Attributes(12).InnerText
'update the table with the CMA name
DataGridView1.Rows.Add(New String() {CMA_Name, CMA_Collector, Original_Name, Log_Server})
Next
Next因此,代码将遍历第一个CMA节点,而不是只查看FW_CKP子节点,而是在XML文件中遍历所有这些节点,并在表中放置额外行(错误的行)。
我怎样才能得到以下结果:
收集器-原始名称-日志服务器名称
日本- Collector_A - FW_A - JAPAN_Pry
日本- Collector_A - FW_B - JAPAN_Pry
日本- Collector_A - FW_C - JAPAN_Pry
美国- Collector_B - FW_D - USA_Pry

我认为您的问题是,您是在全局搜索FW_CKP节点,而不是针对每个CMA节点。
但是,如果所有FW_CKP节点都是CMA节点的唯一直接子节点,则只需使用CMA_Node.ChildNodes:
For Each CMA_Node As System.Xml.XmlElement In CMA_Nodes
'operation inside the CMA balise
CMA_Name = CMA_Node.Attributes(0).InnerText
CMA_Collector = CMA_Node.Attributes(3).InnerText
'loop to go through each FW_CKP nodes
For Each FW_CKP_Node As System.Xml.XmlElement In CMA_Node.ChildNodes
'Operation inside the FW_CKP baslise
Original_Name = FW_CKP_Node.Attributes(3).InnerText
Log_Server = FW_CKP_Node.Attributes(12).InnerText
'update the table with the CMA name
DataGridView1.Rows.Add(New String() {CMA_Name, CMA_Collector, Original_Name, Log_Server})
Next
