如何使用通配符？

Question

我有 XML 插入本地主机名。主机名可以是以下任何一个：

<name>lonmq1111</name>
<name>stoms1111</name>
<name>bqqlk1111</name>
<name>hkgtp1111</name>

根据主机名，下面的脚本需要将正确的网关添加到 XML。例如：

IF <name>lon*<name> OR <name>sto*<name> THEN
    add these gateways
ELSEIF <name>bqq*</name> OR <name>hkg*</name> THEN
    add different gateways
ELSEIF etc.

我有下面的，但它不起作用。关于如何在中间使用通配符有什么想法吗？

$file = Get-Content C:\testnew.xml
if ($file -like ' <name>lon*</name>' -or '<name>sto*</name>') {
  # load XML file
  [xml]$doc = Get-Content "C:\testnew.xml"

  # create node <hostname>
  $comp = $doc.CreateNode('element', 'hostname', '')
  $desc = $doc.CreateTextNode('test')
  $comp.AppendChild($desc)

  # create node <port>
  $sref = $doc.CreateNode('element', 'port', '')
  $desc = $doc.CreateTextNode('1111')
  $sref.AppendChild($desc)

  # create node <gateway> and append child nodes <hostname> and <port>
  $src = $doc.CreateNode('element', 'gateway', '')
  $src.AppendChild($comp)
  $src.AppendChild($sref)

  # append node <gateway> to node <gateways>
  $svc = $doc.SelectSingleNode('//gateways')
  $svc.AppendChild($src)

  # create node <hostname>
  $comp = $doc.CreateNode('element', 'hostname', '')
  $desc = $doc.CreateTextNode('test2')
  $comp.AppendChild($desc)

  # create node <port>
  $sref = $doc.CreateNode('element', 'port', '')
  $desc = $doc.CreateTextNode('2222')
  $sref.AppendChild($desc)

  # create node <gateway> and append child nodes <hostname> and <port>
  $src = $doc.CreateNode('element', 'gateway', '')
  $src.AppendChild($comp)
  $src.AppendChild($sref)

  # append node <Source> to node <Service>
  $svc = $doc.SelectSingleNode('//gateways')
  $svc.AppendChild($src)

  # save XML file
  $doc.Save("C:\testnew.xml")
}

我可以只使用 *lon* 并删除 <name>，但 XML 中的所有其他内容都是自动填充的。我最终可能会遇到 *bqq* 和 *lon* 出现在我想避免的文档中的情况。注意 - 这必须适用于 powershell v2.0.

要编辑的XML：

<?xml version="1.0" encoding="ISO-8859-1"?>
<netprobe compatibility="1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://schema.itrsgroup.com/GA2011.2-110303/netprobe.xsd">
  <selfAnnounce>
    <enabled>true</enabled>
    <retryInterval>60</retryInterval>
    <requireReverseConnection>false</requireReverseConnection>
    <probeName>
      <hostname />
      <data>_</data>
      <port />
      <data>-SA</data>
    </probeName>
    <managedEntity>
      <name>lonms1122</name>
      <attributes>
      </attributes>
      <types>
      </types>
    </managedEntity>
    <gateways>
      <gateway>
      </gateway>
    </gateways>
  </selfAnnounce>
</netprobe>

您的回答很有效。见下方代码

$doc = [xml](Get-Content C:\selfannouncetestnew.xml)

$gateway = switch -Wildcard($doc.SelectSingleNode('//managedEntity/name').InnerText)
{
    "lon*" {
# create node <hostname>
$comp = $doc.CreateNode('element', 'hostname', '')
$desc = $doc.CreateTextNode('test')
$comp.AppendChild($desc)

# create node <port>
$sref = $doc.CreateNode('element', 'port', '')
$desc = $doc.CreateTextNode('1111')
$sref.AppendChild($desc)

# create node <gateway> and append child nodes <hostname> and <port>
$src = $doc.CreateNode('element', 'gateway', '')
$src.AppendChild($comp)
$src.AppendChild($sref)

# append node <gateway> to node <gateways>
$svc = $doc.SelectSingleNode('//gateways')
$svc.AppendChild($src)

# create node <hostname>
$comp = $doc.CreateNode('element', 'hostname', '')
$desc = $doc.CreateTextNode('test2')
$comp.AppendChild($desc)

# create node <port>
$sref = $doc.CreateNode('element', 'port', '')
$desc = $doc.CreateTextNode('2222')
$sref.AppendChild($desc)

# create node <gateway> and append child nodes <hostname> and <port>
$src = $doc.CreateNode('element', 'gateway', '')
$src.AppendChild($comp)
$src.AppendChild($sref)

# append node <gateway> to node <gateways>
$svc = $doc.SelectSingleNode('//gateways')
$svc.AppendChild($src)

$doc.Save("c:\selfannouncetestnew.xml")

    }

    "sto*" {
   # create node <hostname>
$comp = $doc.CreateNode('element', 'hostname', '')
$desc = $doc.CreateTextNode('test3')
$comp.AppendChild($desc)

# create node <port>
$sref = $doc.CreateNode('element', 'port', '')
$desc = $doc.CreateTextNode('3333')
$sref.AppendChild($desc)

# create node <gateway> and append child nodes <hostname> and <port>
$src = $doc.CreateNode('element', 'gateway', '')
$src.AppendChild($comp)
$src.AppendChild($sref)

# append node <gateway> to node <gateways>
$svc = $doc.SelectSingleNode('//gateways')
$svc.AppendChild($src)

# create node <hostname>
$comp = $doc.CreateNode('element', 'hostname', '')
$desc = $doc.CreateTextNode('test4')
$comp.AppendChild($desc)

# create node <port>
$sref = $doc.CreateNode('element', 'port', '')
$desc = $doc.CreateTextNode('4444')
$sref.AppendChild($desc)

# create node <gateway> and append child nodes <hostname> and <port>
$src = $doc.CreateNode('element', 'gateway', '')
$src.AppendChild($comp)
$src.AppendChild($sref)

# append node <gateway> to node <gateways>
$svc = $doc.SelectSingleNode('//gateways')
$svc.AppendChild($src)

$doc.Save("c:\selfannouncetestnew.xml")    

    }

    "bqq*" {
        "barragw:3456"
    }

    "hkg*" {
        "hongkonggw:4567"
    }

    default {
        "defaultgw:5678"
    }
}

$hostname,$port = $gateway -split ':'
# create node <hostname>
$comp = $doc.CreateNode('element', 'hostname', '')
$desc = $doc.CreateTextNode($hostname)
$comp.AppendChild($desc)

# create node <port>
$sref = $doc.CreateNode('element', 'port', '')
$desc = $doc.CreateTextNode($port)
$sref.AppendChild($desc)


$doc.Save("C:\selfannouncetestnew.xml")

为了测试您答案的底部，我将名称更改为 hkggk1122 但没有任何反应。如果名称是 lon(something) 或 sto(something)，它会添加网关。我想让你的解决方案起作用，但不确定你想告诉我用底部做什么。

Answer 1

您的 like 参数中有一个 space。替换

' <name>lon*</name>'

与：

'<name>lon*</name>'

Answer 2

预先解析整个文档，找到 managementEntity/name 节点并使用 switch 决定网关详细信息：

$xml = [xml](Get-Content C:\testnew.xml)

$gateway = switch -Wildcard($xml.SelectSingleNode('//managedEntity/name').InnerText)
{
    "lon*" {
        "londongw:1234"
    }

    "sto*" {
        "stockholmgw:2345"
    }

    "bqq*" {
        "barragw:3456"
    }

    "hkg*" {
        "hongkonggw:4567"
    }

    default {
        "defaultgw:5678"
    }
}

$hostname,$port = $gateway -split ':'

# Create appropriate childnodes and append here
# create node <hostname>
$comp = $doc.CreateNode('element', 'hostname', '')
$desc = $doc.CreateTextNode($hostname)
$comp.AppendChild($desc)

# create node <port>
$sref = $doc.CreateNode('element', 'port', '')
$desc = $doc.CreateTextNode($port)
$sref.AppendChild($desc)

# and so on ...
