Need a Powershell Parse of some HTML code

I have an HTML similar type file. The file gets generated from an app so its not exactly HTML, but I need all the values exported into an csv file.

The file has a Header section and detail section. I don't mind having all the data into 1 table if  makes it easier.

Below I have included sample file to parse and small Powershell script the only thing I can do with Powershell i an still too green. Tried using the HTMLAgilty pack and was unsuccessful.

Here are the column details:
Header Info
codebase, instance_id,guid, id, name, version, registrar, risk_index, force_start, locale_id, template_version, status, score, date, source_object_type,source_object_id, calling_hra_id, external_page_id, in_external_page, from_other_hra, doctorsession_id, obxid, case_id,
loggedin_userid, patient_id, patientname, allow_void,

--Detail Rows
SKIPPED_HISTORY,PAGE id, flush_concepts, update_date, valid,QUESTION id, Score, name, value
Sample2.html
GetHTMLData.txt

PowerShell has a builtin XML object type that will parse the XML content for you:

[xml]$xml = Get-Content C:\users\Jason\Desktop\test.xml

Open in new window


Once the XML object is loaded, you can traverse the object similarly to other PS objects!

once its xml Content any good tutorials on how to extract data from this variable.

And I also see you are passing an xml file.  Could I just rename the file below as xml? Does not seem to have proper tags?

About halfway down this post is a good overview of how navigating XML objects works:

What would you like your CSV file to look like, given this input?  I concur with the assertion that you are working with XML data.

aikimarkCommented:
Another way to get at (parse) the question data would be to apply a regular expression pattern to the contents of the XML file.  The following pattern worked for the question data in the file you posted.
<QUESTION id="(\d+)" Score="(\d+)" name="(.*?)" (?:value="){0,1}(.*?)(?:" ){0,1}/>

Using my method, it would be fairly simple:

[xml]$xml = Get-Content C:\tmp\test.xml
$xml.RESULTSCACHE | export-csv test.csv

@Jason

I don't think that CSV file is what ltorres321 had in mind.

You posted an elegant PS script, however.  It is a bit too simple for the detail I expect is needed.

Please post a couple of lines of CSV data from that XML file.  Do this editing by hand.

Jason RybergTechnical Consultant IVCommented:
I'll be interested to see what kind of table ltorres321 would prefer to use to import into SQL if it's not CSV... seems pretty obvious, but I could be wrong!
0
aikimarkCommented:
Yes.  If you have the data in memory, why persist it to CSV?  Just pump it directly into SQL Server.

However, if the import process is SSIS and the data gets validated, merged or split, I can see a reason why the existing SSIS code might be retained.

Leo TorresSQL DeveloperAuthor Commented:
There is Header data and detail data in this file.

Jason Ryberg : as per your code that actually returns the Header data
which is between  <RESULTSCACHE  and ends at the <SKIPPED_HISTORY value=""/>

There is more data after that that is the Line Detail for this header.

As for CSV it was just to make it easier to get into the database. I was going to use SSIS to move move that data into tables but if Powershell can do it then so be it as well.

Jason your code is nice and very clean but how about the other fields?

Jason RybergTechnical Consultant IVCommented:
I don't think we're very clear on how you're going to need this data formatted.  As aikimark has suggested, do you think you could give a brief example of what the data will look like after it's been formatted?

I see that there are several "Question" data nodes, which can be tabulated by:

$xml.RESULTSCACHE.ChildNodes.ChildNodes | Export-CSV childnodes.csv

Open in new window


But, you're still losing some of your data that way.

You'll need to separate RESULTSCACHE data and QUESTION data, so I would use this approach:
[xml] $xml = Get-Content C:\tmp\test.xml
$xml.ResultsCache | export-csv -NoType C:\tmp\Results.csv
$xml.ResultsCache.Page | % { $_.Question } | export-csv -NoType C:\Tmp\Questions.csv

Open in new window

Qlemo"Batchelor", Developer and EE Topic AdvisorCommented:
Note that Jason's approach only works starting with PS 3. The equivalent code by naming the properties (as in my code snippet) is
$xml.ResultsCache.Page.Question | export-csv -NoType c:\temp\Questions.csv

Open in new window

Leo TorresSQL DeveloperAuthor Commented:
The data just needs to go into a table table. That's just rows and Columns.

Qlemo: that's impressive. Now how do I include the page number as well in the data.

And is there an ID I can create on the fly so when I put this into a table I can tie the header to the details?  Hope that makes sense.

Thanks for the help. I thought this was going to be couple hundred lines of code you did most if it in 3!

Leo TorresSQL DeveloperAuthor Commented:
FYI PS 3 is fine I am using that.

As I also Compare data to what you are producinf Qlemo;

I see this strings of data is missing

Page ID
Flush_Concepts
Update_Date
valid


<PAGE id="1" flush_concepts="0" update_date="7/25/2012 8:43:58 AM" valid="1">

Qlemo"Batchelor", Developer and EE Topic AdvisorCommented:
Correct. We are just dumping the QUESTION part, dismissing any info of PAGE, so you won't find that. I didn't consider the page info important by any means, and probably they aren't. But if you insist in keeping them:
[xml]$xml = Get-Content C:\tmp\Sample2.html
$xml.ResultsCache | export-csv -NoType C:\tmp\Results.csv
$xml.ResultsCache.Page | % { $page = $_; $_.Question | select `
  @{n='PageID'        ; e = {$page.ID}},
  @{n='flush_concepts'; e = {$page.flush_concepts}},
  @{n='valid'         ; e = {$page.valid}},
  @{n='update_date'   ; e = {$page.update_date}},
  ID, Score, Value
} | export-csv -NoType C:\tmp\Questions.csv

Open in new window

The ResultsCache ID stuff depends on how it should be built. If you we can use instance_id, all we have to do is to include that in each question row, similar to the page data above.

Assuming that ltorres321 wants the skipped_history data, a slight tweak of Qlemo's script should produce the desired results in any version of PS.
[xml] $xml = Get-Content '\\pcna-02\mydocs\ltorres\My Documents\_CCA\Sample2.html'
$SH = $XML.resultscache.skipped_history
$xml.ResultsCache.Page | % { $page = $_; $_.Question | select `
  @{n='SkippedHistory'        ; e = {$SH.value}},
  @{n='PageID'        ; e = {$page.ID}},
  @{n='flush_concepts'; e = {$page.flush_concepts}},
  @{n='valid'         ; e = {$page.valid}},
  @{n='update_date'   ; e = {$page.update_date}},
  ID, Score, Value
} | export-csv -NoType '\\pcna-02\mydocs\ltorres\My Documents\_CCA\Sample2.csv'

Open in new window

I had worked up a nested foreach solution, but the Qlemo code is simpler and probably performs better.

Wow, Excellent I will close this here for now. I will try to get this data into SQL tables. If I cant I will post another question to be fair. Thanks to all for the exceptional HELP! I need every bit of it.
