通过 PowerShell Web 服务显示 SP 列表

Question

我正在尝试检索 SP 列表中的项目并显示“ows_Title”、“ows_Latitude”、“ows_Longitude”和“ows_LocationDetails”字段。我正在通过 Web 服务访问列表，但我当前的代码不断返回大量 XML，我不确定从这里去哪里。任何帮助将不胜感激。

# Connect to web service
$uri = "http://teams.COMPANY.intranet/_vti_bin/lists.asmx"
$service = New-WebServiceProxy -uri $uri -Namespace SpWs  -UseDefaultCredential 
$service.url = "http://teams.COMPANY.intranet/sites/MYSITE/_vti_bin/lists.asmx"
$xmlDoc = new-object System.Xml.XmlDocument            
$listName = "MapDetails"  
$viewFields = $xmlDoc.CreateElement("ViewFields")
$query = $xmlDoc.CreateElement("Query")          
#$viewfields.InnerXml = "<ViewFields><FieldRef Name='ows_Latitude'></FieldRef><FieldRef Name='ows_Longitude'></FieldRef></ViewFields>"
$list = $service.GetListItems($listname,$null, $null, $viewfields,$null,$null,$null)
$list.outerxml

这个输出：

如果已经回答了这个问题，请随时为我指明正确的方向。

注意：由于这项任务的性质，很遗憾我不能使用 CSOM。

Answer 1

Powershell 具有以友好方式处理 XML 的内置功能。使用 [xml] 类型前缀将字符串转换为 XML 对象很容易，如下所示：

PS H:\> [xml]$listXml = $list.outerxml

然后您可以使用点符号来访问 XML 中的元素：

PS H:\> $listXml

    listitems
    ---------
    listitems

PS H:\> $listXml.listitems  

    s     : uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882
    dt    : uuid:C2F41010-65B3-11d1-A29F-00AA00C14882
    rs    : urn:schemas-microsoft-com:rowset
    z     : #RowsetSchema
    xmlns : http://schemas.microsoft.com/sharepoint/soap/
    data  : data

PS H:\> $listXml.listitems.data

     ItemCount        row
     ---------        ---
     2                {z:row, z:row}

在这种情况下，您可以通过访问listitems.data.row 集合中的各个元素来访问各个列表项。

PS H:\> $listXml.listitems.data.row[0]

    ows_ID                   : 2
    ows_ContentTypeId        : 0x010094EFD209B7CD4E1AB7F9577...
    ows_ContentType          : MapDetails
    ows_Title                : UK
    ows_Modified             : 2015-10-28 14:49:58
     [...]
    ows_Latitude             : 1.23000000000000
    ows_Longitude            : 0.560000000000000
    ows_LocationDetails      : <div>Top united Kingdom Hits</div>
