Automating Web Query import

R

Roger on Excel

I use hyperlinks for chemicals that access a webpage for the individual
compounds showing tables of data for that chemical.

I have a large list of chemicals and I want to automate the downloading of
specific data in the tables from the web pages.

The chemical data is stored in the same format of tables on each webpage.

Can anyone help?

Thanks,

Roger

Ther are tow basic mathods that can be used.

1) Perform a web query. First setup a Reord Macro (Tools - Macro - Start
Recording).. then perform one query manually by going to Data - Import
External Data - New Web Query. Next modify the the recorded macro as
required to add a loop changing the chemicals and the destination location so
the data doesn't over-write each other.

If one above doesn't work

2) Open an Internet Explorer application in Excel. through the Internet
Explorer request each chemical and extract each results through the Internet
Explorer Application.

Let me know which approach you want to use. I can help with both approaches.

Thhe code below was very simple. I did it in about 15 minutes. It gets the
names of all the chemicals. I will work on the rest later.


Sub Getchemicals()

Set TempSht = Sheets.Add(after:=Sheets(Sheets.Count))
TempSht.Name = "Temp"
Set ChemicalSht = Sheets.Add(after:=Sheets(Sheets.Count))
ChemicalSht.Name = "Summary"

URLFolder =
"URL;http://www.ilo.org/public/english/protection/safework/cis/products/icsc/dtasht/"
ChemicalRowCount = 1
For i = 0 To 25
AlphaLetter = Chr(Asc("a") + i)

TempSht.Cells.ClearContents

With TempSht.QueryTables.Add(Connection:= _
URLFolder & AlphaLetter & "_index.htm", _
Destination:=TempSht.Range("A1"))

.Name = "a_index"
.FieldNames = True
.RowNumbers = False
.FillAdjacentFormulas = False
.PreserveFormatting = True
.RefreshOnFileOpen = False
.BackgroundQuery = True

.WebFormatting = xlWebFormattingNone
.WebPreFormattedTextToColumns = True
.WebConsecutiveDelimitersAsOne = True
.WebSingleBlockTextImport = False
.WebDisableDateRecognition = False
.WebDisableRedirections = False
.Refresh BackgroundQuery:=False
End With

'move data from tempory sheet to chemical sheet
TempRowCount = 17
Do While Range("C" & TempRowCount) <> ""
ChemicalSht.Range("A" & ChemicalRowCount) = _
TempSht.Range("C" & TempRowCount)

ChemicalRowCount = ChemicalRowCount + 1
TempRowCount = TempRowCount + 1
Loop
Next i

TempSht.Cells.ClearContents

End Sub

I had to switch to method 2 to get each chemical webpage. Try this code.
Which data do you need? try using method one manually (Data - Import
External Data - New Web Query) with one of the webpages from the code below
and select one or more tables and see if the results are usable.

I will help as required.


Sub Getchemicals2()


Set ChemicalSht = Sheets.Add(after:=Sheets(Sheets.Count))
ChemicalSht.Name = "Chemicals"

Set IE = CreateObject("InternetExplorer.Application")
IE.Visible = True

URLFolder = _

"http://www.ilo.org/public/english/protection/safework/cis/products/icsc/dtasht/"
ChemicalRowCount = 1
For Letters = 0 To 25
AlphaLetter = Chr(Asc("a") + Letters)

URL = URLFolder & AlphaLetter & "_index.htm"

'get web page
IE.Navigate2 URL
Do While IE.readyState <> 4
DoEvents
Loop

Do While IE.busy = True
DoEvents
Loop

H2Found = False
For Each itm In IE.document.all
If H2Found = False Then
If itm.tagname = "H2" Then
H2Found = True
End If
Else

If itm.tagname = "A" Then
If itm.innertext = "" Then Exit For

'chemical name
ChemicalSht.Range("A" & ChemicalRowCount) = itm.innertext
'webpage
ChemicalSht.Range("B" & ChemicalRowCount) = itm.href

ChemicalRowCount = ChemicalRowCount + 1
End If
End If
Next itm

Next Letters


End Sub

Joel,

This is excellent.

Thanks for your advice.

How would I download other information from other tables - for example I
would like to input further data from the tables into further adjacent
columns so one can use the table as a vlookup source?

I see you use references like itm.innertext - does this select individual
line items from the tables on the web page?

Thanks, Roger

Right now I'm not sure which is the better method to use to get the data from
the tables. It depends on which items from the tables you ae looking for. I
used method 1 (web query) to download everything from the table. Some of the
data was hard to manipulate into ccolumn format on a spreadsheet. We would
have to do something like I did to get the chemical names. first perform a
query into a temporary page and then move the data to a summary page.

When I work with the Internet Explorer it is harder to figure out how to get
the data, but the coding usually is simplier. I use a few tricks to get the
data.

1) I look at the source code for the webpage by using the Internet Explorer
menu View - Source. I first look for the data I'm trying to extract. I look
in particular for tags. a tag with look like the following


<abc
.......................................................................
/abc>

The tag would be "abc". The tags are usually nested and there is always an
opening (<) and closing (>) character. The closing marker. The closing
marker may not have the tag name and may just lmay be a forward slah followed
by an angle bracket (/>).

I also look for classname which are in the source

id="msviRegionId"

The Clssname is always id= followed by the name in double quotes.

Using code you can get these items using the folowwing two statements

Set ClassB = IE.document.getelementsbytagname("abc")

Set RegionID = IE.document.getElementById("msviRegionId")

Each will return multiple items and to get each item you can use a look like
this

for each itm in ClassB
'add code here
next itm

2) The data is always in the innertext property. It depends how the data is
organized which method(s) I use to get the data. I usually dump the data
first to a spreadsheet using the following code

RowCount = 1
for each itm in IE.Document.All
Range("A" & RowCount) = itm.tagname
Range("B" & RowCount) = itm.classname
Range("C" & RowCount) = itm.innertext
RowCount = RowCount + 1
next itm

Note: innertext can sometimes by very long a cause memory errors. I
sometimes have to limit the data using left
Range("B" & RowCount) = left(itm.classname,1024)


or

RowCount = 1
for each itm in ClassB
Range("A" & RowCount) = itm.tagname
Range("B" & RowCount) = itm.classname
Range("C" & RowCount) = itm.innertext
RowCount = RowCount + 1
next itm

3) I also you break point and watch items. I will put a break in one of the
FOR loop above by left click with mouse on the line of code to bring the
cursor to the line. Then Pressing F9 to add Break Point.

Then I add a WATCH item for debugging. I will highlight ITM with the mouse
and then right click. Next I will select ADD WATCH and press OK on dialog
window to add the watch. Finally, I will press the plus (+) sign on the
watch window to see the data. Sometimes you can find the data in linked
lists under "children". There are other properties that are sometimes useful
like href (I used thsi to get the URL addresses of the chemicals).

Thanks for looking at this Joel,

I will take a look at what you suggest later today. It sounds quite
complicated, but I am keen to learn more so will work through your
suggestions and see what I get.

Best regards,

The best way of doing this way to use Internet Explorer to get the chemical
names and webpages. It was better to use web query to get the actual data.
Here is all the code. It was mostly copying and modifying the same code over
and over and over again.

I have an extra line of code "Exit For" to allow only the first chemical to
run. Make sure you verify what I did before removing line and running 5600
chemicals

I found one error. the molecular Mass was in the wrong column


from

'Move molecular mass
DataSht.Range("g" & RowCount) = Trim(Mid(c.Value, InStr(c.Value, ":")
+ 1))

to

'Move molecular mass
DataSht.Range("H" & RowCount) = Trim(Mid(c.Value, InStr(c.Value, ":")
+ 1))

I tested for a few more chemicals and found that not all chemicals have the
same properties. You have to remove some of the STOP and Error messages.
Also you may have to add more columns for properties I do not have coded.

Thanks so much for this Joel,

I will check it out tomorrow as im not feeling well this evening. I noticed
that some of the fields have more data than others - a tricky problem for
sure.

All the best,

Roger

The macro I provided should be carefully checked. I used only a couple of
chemicals to check my results. I have noticed a few problems shown below

For debugging and to run the code in pieces you can change these statement
in getData(). when you run the code on the full set of data I would run it
in sections. Maybe 500 to 1000 chemicals at a time. If the code ran 10
chemicals a minute, it would take about 10 hours to do all the chemicals.

from
LastRow = .Range("A" & Rows.Count).End(xlUp).Row
Set Chemicals = .Range("A1:A" & LastRow)
NewRowCount = 4
To

FirstRow = 1
LastRow = .Range("A" & Rows.Count).End(xlUp).Row
LastRow = 5
Set Chemicals = .Range("A" & FirstRow & ":A" & LastRow)
NewRowCount = FirstRow + 3 'where the first chemical is put on the
"Data" worksheet

Note: Remeber to take out the EXIT FOR statement which only allows one
chemical to get processed.


To run the Code first get chemicals running the macro Getchemicals2(). You
only need to run this macro once. Then run the Macro GetData() which will
use the webpages from Getchemicals2() to get the rest of the data.


1) Some items I'm look at only one row of data on the Temp sheet and others
I collected multiple rows by using a Do Loop and looking for the 1st blank
row to terminate. I noticed that on the "Notes" section I'm looking a only
one row where are some chemicals there are multiple rows for Notes.

Also Emergency response I'm only looking at 1 row and missing the NFPA
information.

2) I didn't include the chemical composition like C2H1O3. It is in the row
directly above the Molecular Mass

3) I don't know if I included all the data because I used only a couple of
chemicals as examples. There may be other properties (especially in the
Important Data) that I may have missed.

4) The PDF printout of the chemicals has a section on Additional Information
but I didn't see any chemicals with this information. Again I only looked at
a few chemicals.

I found some errors and didn't like how I was specifying the column. I
converted the column Leeter to constants so it would be easier to add, delete
and move columns. I also the following:

1) Molecular formula
2) Added to Emergeny Response getting multiple rows of data
3) Added to Notes getting multiple rows of data

I use hyperlinks for chemicals that access a webpage for the individual
compounds showing tables of data for that chemical.

I have a large list of chemicals and I want to automate the downloading of
specific data in the tables from the web pages.

The chemical data is stored in the same format of tables on each webpage.

Can anyone help?

Thanks,

Roger

Do you always want to obtain the same info, just for a diffrerent
chemical? If so, specifically what info do you want?..ron

Ron: Look at the webpage below.  There are over 5000 chemicals each with
different properties and warnings!

Yes, but depending what information is required, perhaps capturing it
a) from the source code or b) by obtaining specific tables might be a
reasonable solution. For example, Table 10 contains all of the
"Important Data" information.

Set cTables = ie.Document.getElementsByTagname("table")
s = cTables(10).innertext
Debug.Print s

and "s" then contains

IMPORTANT DATA
Physical State; Appearance
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.
Physical dangers
The vapour is heavier than air and may travel along the ground;
distant ignition possible.
Chemical dangers
The substance can form explosive peroxides on contact with strong
oxidants such as acetic acid, nitric acid, hydrogen peroxide. Reacts
with chloroform and bromoform under basic conditions, causing fire and
explosion hazard. Attacks plastic.
Occupational exposure limits
TLV: 500 ppm as TWA, 750 ppm as STEL; A4 (not classifiable as a human
carcinogen); BEI issued; (ACGIH 2004).
MAK: 500 ppm 1200 mg/m³ Peak limitation category: I(2); Pregnancy risk
group: D; (DFG 2006).Routes of exposure
The substance can be absorbed into the body by inhalation and through
the skin.
Inhalation risk
A harmful contamination of the air can be reached rather quickly on
evaporation of this substance at 20°C ; on spraying or dispersing,
however, much faster.
Effects of short-term exposure
The vapour irritates the eyes and the respiratory tract. The substance
may cause effects on the central nervous system, liver, kidneys and
gastrointestinal tract.
Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. The
substance may have effects on the blood and bone marrow.

Again, depending upon which pieces of data for each chemical are
required, perhaps one of these approaches might prove useful...ron

Whoops, I checked a few more chemicals and found that Table 10 is not
always the "Important Data" table. Still, I'd like to see an answer
to my original question - what specific data fields does Roger want to
capture?..ron

Ron: It looks a little easier to get the data from the webpage your way than
mine. Your has an advantage of getting the formated data from the innerhtml
property.
