ConvertTo-XmlString #
SYNOPSIS #
This PowerShell function converts ADO (ActiveX Data Objects) field objects into XML strings. It accepts various data types and handles NULL values according to the specified options. Source code on GitHub.
SYNTAX #
ConvertTo-XmlString [[-adoField] <__ComObject>] [-includeEmpty] [-ProgressAction <ActionPreference>]
[<CommonParameters>]
DESCRIPTION #
The ConvertTo-XmlString function in PowerShell accepts an ADO field object and an optional switch -includeEmpty, which specifies whether empty values should be included in the output or not. The function checks the data type of the passed object and converts its value accordingly into an XML string. For NULL values, it returns the default value or an empty value (depending on the -includeEmpty option).
EXAMPLES #
Example 1: Convert an ado date field to an XML string #
# Create a recordset with a field of type adDBTimeStamp
$rs = New-Object -ComObject ADODB.Recordset
$rs.Fields.Append("MyDateField", $adDBTimeStamp)
$rs.Open()
# Add a new record and set the value to the current date
$rs.AddNew()
$rs.Fields("MyDateField").Value = Get-Date
# Retrieve the ADO object
$adoField = $rs.Fields("MyDateField")
# Convert the ADO object to an XML string using the ConvertTo-XmlString function
$convertedXmlString = ConvertTo-XmlString -adoField $adoField
# Output the converted XML string
Write-Output $convertedXmlString
# Close the recordset and release the used memory
$rs.Close()
[System.Runtime.InteropServices.Marshal]::ReleaseComObject($rs) | Out-Null
In this example, an ADO recordset is created with a field of type adDBTimeStamp. A new record is added, and the field value is set to the current date. Then, the ADO object is converted to an XML string using the ConvertTo-XmlString function, and the output is displayed. Finally, the recordset is closed and the used memory is released.
