I am trying to parse an XML file that contains an element

XML

<DateOut>2/11/2015</DateOut>

The date is arbitrary and changes per parent node.

XML

<?xml version="1.0" encoding="utf-8"?>
<CurrentJobs>
  <Job>
    <JobID>00d5dafa-f1d4-45e0-9744-904162428cab</JobID>
    <Status>a-current</Status>
    <CustomerName>Tennessee Valley Towing</CustomerName>
    <PurchaseOrder>TVT</PurchaseOrder>
    <Artwork>images\TVT.png</Artwork>
    <DateIn>3/25/2015 </DateIn>
    <DateOut>4/21/2015 </DateOut>
    <Rush>1</Rush>
    <Details>White Grommet Flag</Details>
    <Notes></Notes>
    <Color1F>PANTONE 1585 C</Color1F>
    <Color2F></Color2F>
    <Color3F></Color3F>
    <Color4F></Color4F>
    <Color5F></Color5F>
    <Color6F></Color6F>
    <Color1B></Color1B>
    <Color2B></Color2B>
    <Color3B></Color3B>
    <Color4B></Color4B>
    <Color5B></Color5B>
    <Color6B></Color6B>
    <Count>40</Count>
    <Sample></Sample>
    <Taken>Leigh</Taken>
  </Job>
  <Job>
    <JobID>010eb5b4-926c-4bef-b1e6-f4df0f55d899</JobID>
    <Status>b-complete</Status>
    <CustomerName>St Michael</CustomerName>
    <PurchaseOrder>2014 Book Bee</PurchaseOrder>
    <Artwork>images\2014 Book Bee.png</Artwork>
    <DateIn>2/23/2015 </DateIn>
    <DateOut>2/27/2015 </DateOut>
    <Rush>1</Rush>
    <Details>Sport Grey T</Details>...

I want to compare the DateOut element to the 'Today' date and if the DateOut is > 30 day timespan, I want to remove the entire parent node <job>.

I also want to deleted the PNG file defined in <artwork> element.

I apologize if I'm using the wrong terms (element vs. node), I'm still ind of new to XML.

I've gotten a start with the code below...

VB

Public Sub CheckOldDates()
    'load xml
    Dim o As ObjectDataProvider
    Dim xele As XElement = XElement.Load("\\ARTSTATION\Users\Public\XML Job Board\current_jobs.xml")

    'check for completed job
    Dim completed = (From job In xele.Descendants("Job")
                     Where job.Element("Status").Value = "b-complete" _
                     Select job) '.SelectMany '.SingleOrDefault()

    'if older than 30 days completed, delete
    Dim ts As TimeSpan = Today - Convert.ToDateTime(completed.Element("DateOut").Value)

    MsgBox(ts.TotalDays)

    'Delete image png

    'save xml
    'xe.Save("\\ARTSTATION\Users\Public\XML Job Board\current_jobs.xml")

    'o = FindResource("jobs")
    'o.Refresh()
End Sub

Do you want to delete jobs where the job has been completed 30 days ago?

See an example:

VB

Dim sFileName as String = "EnterFullFileNameHere.xml"
'load document
Dim xDoc = XDocument.Load(sFileName)

'get date = Today - 30 days
Dim mDate As Date = DateTime.Today().AddDays(-30)
'get pictures to delete
Dim picturesToDelete = From job in xDoc.Root.Descendants("Job") _
            Where (job.Elements("Status").Value = "b-complete" And job.Elements("DateOut").Value <  mDate) _
            Select job.Elements("Artwork").Value
'loop through the pictures..
For Each p in picturesToDelete
    'display picture name
    Console.WriteLine("{0}", p)
    'ToDo: delete picture by its name here
Next

[EDIT]
Based on the same logic you can get jobs to delete

VB

Dim jobsToDelete = From job in xDoc.Root.Descendants("Job") _
            Where (job.Elements("Status").Value = "b-complete" And job.Elements("DateOut").Value <  mDate) _
            Select job
jobsToDelete.Remove()
xDoc.Save("NewOrOldFileName.xml")

Good luck!
