Question

我有XML插入本地主机名。主机名可以是以下任何一种：

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

根据主机的名称，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.

我有以下内容，但它不起作用。关于如何在中间使用通配符的任何想法？

$file = Get-Content C:\testnew.xml
if ($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")
}

我可以使用*lon*并删除<name>，但XML中的所有其他内容都会自动填充。我最终可能会遇到*bqq*和*lon*在我希望避免的文档中的情况。注意 - 这必须适用于powershell v2.0。

将要编辑的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">

    <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>

@Mathias

你的答案很有效。请参阅以下代码

$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")

为了测试答案的底部，我将名称更改为hkggk1122，但没有任何反应。如果名称为lon(something)或sto(something)，则会添加网关。我想让你的解决方案工作，但不确定你要告诉我你的底部部分。

Answer 1

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

$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 ...

Answer 2

like参数中有空格。取代

' <name>lon*</name>'

使用：

'<name>lon*</name>'

如何使用通配符？
