Code Snippets
Useful code snippets to help you with those complex scripts.
List fields on template
Example: The following demonstrates how to list all of the fields of a template excluding the Standard Template fields.
1
# Create a list of field names on the Standard Template. This will help us filter out extraneous fields.

$standardTemplate = Get-Item -Path "master:" -ID "{1930BBEB-7805-471A-A3BE-4858AC7CF696}"
3
$standardTemplateTemplateItem = [Sitecore.Data.Items.TemplateItem]$standardTemplate
4
$standardFields = $standardTemplateTemplateItem.OwnFields + $standardTemplateTemplateItem.Fields | Select-Object -ExpandProperty key -Unique
5
​
6
$itemTemplate = Get-Item -Path "master:" -ID "{76036F5E-CBCE-46D1-AF0A-4143F9B557AA}"
7
$itemTemplateTemplateItem = [Sitecore.Data.Items.TemplateItem]$itemTemplate
8
$itemTemplateFields = $itemTemplateTemplateItem.OwnFields + $itemTemplateTemplateItem.Fields | Select-Object -ExpandProperty key -Unique
9
​
10
$filterFields = $itemTemplateFields | Where-Object { $standardFields -notcontains $_ } | Sort-Object

3
$htmlDocument.LoadHtml($html)
4
foreach($x in $htmlDocument.DocumentNode.SelectNodes("//li")) {
5
$x.InnerText;
6
}

foreach($x in $htmlDocument.DocumentNode.Descendants()) {
15
if($x.Name -ne "img" -and ![string]::IsNullOrEmpty($x.Text)) {

4
$workflowProvider = $db.WorkflowProvider

​
6
foreach($version in $item.Versions.GetVersions()) {
7
$workflowEvents = $workflowProvider.HistoryStore.GetHistory($version)
8
foreach($workflowEvent in $workflowEvents) {
9
"[$($workflowEvent.Date)] ($($workflowEvent.User)) $(($workflowEvent.Text -replace '(\r|\n)',''))"
