# Code Snippets
## List fields on template
**Example:** The following demonstrates how to list all of the fields of a template excluding the Standard Template fields.
```powershell
# 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}"
$standardTemplateTemplateItem = [Sitecore.Data.Items.TemplateItem]$standardTemplate
$standardFields = $standardTemplateTemplateItem.OwnFields + $standardTemplateTemplateItem.Fields | Select-Object -ExpandProperty key -Unique
$itemTemplate = Get-Item -Path "master:" -ID "{76036F5E-CBCE-46D1-AF0A-4143F9B557AA}"
$itemTemplateTemplateItem = [Sitecore.Data.Items.TemplateItem]$itemTemplate
$itemTemplateFields = $itemTemplateTemplateItem.OwnFields + $itemTemplateTemplateItem.Fields | Select-Object -ExpandProperty key -Unique
$filterFields = $itemTemplateFields | Where-Object { $standardFields -notcontains $_ } | Sort-Object
```
## Media item url
**Example:** The following demonstrates how to generate the public facing url from a media item.
```powershell
$item = Get-Item -Path "master:{04DAD0FD-DB66-4070-881F-17264CA257E1}"
$siteName = "website"
$site = [Sitecore.Sites.SiteContextFactory]::GetSiteContext($siteName)
New-UsingBlock (New-Object Sitecore.Sites.SiteContextSwitcher $site) {
[Sitecore.Resources.Media.MediaManager]::GetMediaUrl($item)
}
# /-/media/default-website/cover.jpg
```
## Parse Html
**Example:** The following demonstrates the use of the **HtmlAgilityPack** for parsing html.
```powershell
$html = ""
$htmlDocument = New-Object -TypeName HtmlAgilityPack.HtmlDocument
$htmlDocument.LoadHtml($html)
foreach($x in $htmlDocument.DocumentNode.SelectNodes("//li")) {
$x.InnerText;
}
```
**Example:** The following demonstrates how to update text in the document and exclude certain nodes.
```powershell
$html = @"
kitchen
kitchen
"@
$htmlDocument = New-Object -TypeName HtmlAgilityPack.HtmlDocument
$htmlDocument.LoadHtml($html)
foreach($x in $htmlDocument.DocumentNode.Descendants()) {
if($x.Name -ne "img" -and ![string]::IsNullOrEmpty($x.Text)) {
$x.Text = $x.Text.Replace("kitchen", "sink")
}
}
$htmlDocument.DocumentNode.OuterHtml
```
**Example:** The following demonstrates how to remove empty paragraph tags in an html field.
[Sitecore Stack Exchanage](https://sitecore.stackexchange.com/a/20845/95)
**Example:** The following demonstrates removing style attributes from the html.
```powershell
$html = @"
Some Text
"@
$htmlDocument = New-Object -TypeName HtmlAgilityPack.HtmlDocument
$htmlDocument.LoadHtml($html)
$nodes = $htmlDocument.DocumentNode.SelectNodes("//@style");
foreach($node in $nodes) {
$node.Attributes["style"].Remove()
}
$htmlDocument.DocumentNode.OuterHtml
```
## Workflow History
**Example:** The following prints the workflow history of the home item.
```powershell
$item = Get-Item -Path "master:" -Id "{110D559F-DEA5-42EA-9C1C-8A5DF7E70EF9}"
$db = Get-Database -Name "master"
$workflowProvider = $db.WorkflowProvider
foreach($version in $item.Versions.GetVersions()) {
$workflowEvents = $workflowProvider.HistoryStore.GetHistory($version)
foreach($workflowEvent in $workflowEvents) {
"[$($workflowEvent.Date)] ($($workflowEvent.User)) $(($workflowEvent.Text -replace '(\r|\n)',''))"
}
}
```
## Restore Recycle bin items
**Example:** The following restores items in the media library that were removed yesterday. [Credit](https://gist.github.com/technomaz/58890edff903123083c77ad8f1b1b2e2) @technomaz.
```powershell
Write-Host "Restoring items recycled after $($archivedDate.ToShortDateString())"
foreach($archive in Get-Archive -Name "recyclebin") {
Write-Host " - Found $($archive.GetEntryCount()) entries"
$entries = $archive.GetEntries(0, $archive.GetEntryCount())
foreach($entry in $entries) {
if($entry.ArchiveLocalDate -ge $archivedDate) {
Write-Host "Restoring item: $($entry.OriginalLocation) {$($entry.ArchivalId)}on date $($entry.ArchiveLocalDate)"
$archive.RestoreItem($entry.ArchivalId)
} else {
Write-Host "Skipping $($entry.OriginalLocation) on date $($entry.ArchiveLocalDate)"
}
}
}
```
## Purge Recycle bin items
**Example:** The following will incrementally purge items from the recycle bin (master db) with a progress counter.
```powershell
$database = Get-Database -Name "master"
$archiveName = "recyclebin"
$archive = Get-Archive -Database $database -Name $archiveName
$items = Get-ArchiveItem -Archive $archive
$count = 0
$total = $items.Count
foreach($item in $items) {
$count++
if($count % 100 -eq 0) {
Write-Host "[$(Get-Date -Format 'yyyy-MM-dd hh:mm:ss')] $([math]::round($count * 100 / $total, 2))% complete"
}
$item | Remove-ArchiveItem
}
Write-Host "Completed processing recycle bin"
```
## Run JavaScript
**Example:** The following logs messages to the browser console and then alerts the user with a message.
```powershell
1..5 | ForEach-Object {
Start-Sleep -Seconds 1
Invoke-JavaScript -Script "console.log('Hello World! Call #$($_) from PowerShell...');"
}
Invoke-JavaScript -Script "alert('hello from powershell');"
```
## Remoting
**Example:** [Remote Package Installation](https://gist.github.com/michaellwest/14e9ef98f9e8b450c1b39813d13cbc50)
```powershell
Import-Module -Name SPE -Force
$packageName = "$($SitecorePackageFolder)\[PACKAGE].zip"
$session = New-ScriptSession -Username "admin" -Password "b" -ConnectionUri "https://remotesitecore"
Test-RemoteConnection -Session $session -Quiet
$jobId = Invoke-RemoteScript -Session $session -ScriptBlock {
[Sitecore.Configuration.Settings+Indexing]::Enabled = $false
Get-SearchIndex | ForEach-Object { Stop-SearchIndex -Name $_.Name }
Import-Package -Path "$($SitecorePackageFolder)\$($using:packageName)" -InstallMode Merge -MergeMode Merge
[Sitecore.Configuration.Settings+Indexing]::Enabled = $true
} -AsJob
Wait-RemoteScriptSession -Session $session -Id $jobId -Delay 5 -Verbose
Stop-ScriptSession -Session $session
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://doc.sitecorepowershell.com/code-snippets.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
