XPath Advanced query (contains, text()...) implemented?

[Damien]

Hi,
I m testing install aware X3 for my company, before decide to buy it or not.
I m currently testing some XPath queries, but I cant make some work.
I need to find a node if text contains something. I also tried with equals comparaison.

This is my InstallAware "human readable" code:

Code: Select all

Evaluate Query //Client[@Name="LePicard"]/Peripherique[contains(text(),"bbb")]/@Id on XML file $InstallerFilesPath$\Clients_Peripheriques.xml, get result into variable SelectedDeviceId as type Full XML String

and

Code: Select all

Evaluate Query //Client[@Name="LePicard"]/Peripherique[text()="bbb"]/@Id on XML file $InstallerFilesPath$\Clients_Peripheriques.xml, get result into variable SelectedDeviceId as type Full XML String

Equality works well with parameters:

Code: Select all

Evaluate Query //Client[@Name="LePicard"]/Peripherique[@TerminalName="bbb"]/@Id on XML file $InstallerFilesPath$\Clients_Peripheriques.xml, get result into variable SelectedDeviceId as type Full XML String

but not contains

Code: Select all

Evaluate Query //Client[@Name="LePicard"]/Peripherique[contains(@TerminalName,"bbb")]/@Id on XML file $InstallerFilesPath$\Clients_Peripheriques.xml, get result into variable SelectedDeviceId as type Full XML String

So are contains(), text() or other w3C recommandation xpath functions implemented?
Or if there is a different query to do this, how can I do it?

Thanks.

There is my XML code sample:

Code: Select all

<?xml version="1.0" encoding="UTF-8" ?>
<Clients>
   <Client Name="Neolis">
      <Peripherique Id="1" TerminalName="Tab01" Type="Tablette">Tab01 - Tablette</Peripherique>
      <Peripherique Id="2" TerminalName="Tab02" Type="Tablette">Tab02 - Tablette</Peripherique>
      <Peripherique Id="3" TerminalName="Siege" Type="Serveur">Siege - Serveur</Peripherique>
   </Client>
   <Client Name="Boucheron">
      <Peripherique Id="4" TerminalName="Terminal 01" Type="Tablette">Terminal 01 - Tablette</Peripherique>
      <Peripherique Id="5" TerminalName="Terminal 02" Type="Tablette">Terminal 02 - Tablette</Peripherique>
      <Peripherique Id="6" TerminalName="Siege Boucheron" Type="Serveur">Siege Boucheron - Serveur</Peripherique>
   </Client>
   <Client Name="LePicard">
      <Peripherique Id="7" TerminalName="Tablette 01" Type="Tablette">Tablette 01 - Tablette</Peripherique>
      <Peripherique Id="8" TerminalName="Tablette 02" Type="Tablette">Tablette 02 - Tablette</Peripherique>
      <Peripherique Id="9" TerminalName="Maison Mere" Type="Serveur">Maison Mere - Serveur</Peripherique>
      <Peripherique Id="10" TerminalName="bbb" Type="Serveur">bbb</Peripherique>
   </Client>
</Clients>

Dear Damien,

unfortunately xpath functions cannot be used.

You may alternatively use;
(copy and paste within the script editor the code below)

Code: Select all

~InstallAware Clipboard Data~
~MessageBox~
~{A6B0B67B-52C7-4AAA-A0D4-192BDFC44DA5}~
~~
~$XML_PATH$~
~0~
~1~
~~
~Evaluate XPath Query~
~{A71A5A87-B7C5-4E59-8252-B5C73716B7A3}~
~$SUPPORTDIR$\XMLFile2.xml~
~//Client[@Name="LePicard"]/Peripherique/@TerminalName~
~XML_PATH~
~2~
~Set Variable~
~{A62FEEB6-FB31-4BE3-B049-C8DEAFBBEBD7}~
~XML_PATH$MYAH$MYAH$FALSE~
~~


The above snippet returns the following node value (where each result is delineated with the $NEWLINE$ pre-defined variable);
Tablette 01
Tablette 02
Maison Mere
bbb

Finally you can use the "Parse String" command to split the value returned or alternatively you may use the IF statement, to operate a conditional evaluation based on the presence of a specific value.

Hope this helps you.

Ok, thanks it help me .

I want to ask you something else i saw when i did comparaison:
I got a value from listbox (from XPATH Query), and when I compared it in a foreach loop on the same XPATH Query, nothing was matching with equality, or contains. I spend few hours to finaly write output in a file, and understand the selected value on the listbox contains the $NEWLINE$ var, and not the item on the foreach iteration.

So, is there a way to prevent this, to only get the real value? or should I parse listbox ouput var?

[FrancescoT]

Dear Damien,

I am not quite sure to follow your question.

In case you are referring to the "value format" returned from a Listbox, this depends on the listbox's items selection.
If multiple values are returned these will be delineated with the $NEWLINE$ pre-defined variable.

Hope this helps you.

[Damien]

Sorry, i was not working last week.

The listbox is not in multi select mode.
The listbox items : item1$NEWLINE$item2$NEWLINE$item3

Code: Select all

Set variable SelectedItem to   // listBox variable output
Set variable Item to item1 // at runtime I select item1 in listbox
Set variable Equality to false

if SelectedItem equals Item
   Set Equality to true
end
MessageBox: Selected Item, Select Item : $SelectedItem$  $NEWLINE$ $SelectedItem$ equals $Item$ : $Equality$


I really dont understand why this is implemented like this, the selected item must not contain the separator on single select... Or did I missed a listbox option?

[FrancescoT]

Dear Damien,

for example, you should instead;

Code: Select all

Set Variable SELECTED_VALUES to
Set Variable LISTBOXVALUES to DSN1$NEWLINE$DSN2$NEWLINE$DSN3$NEWLINE$DSN4
Display Dialog: prereq, wait for dialog to return (modal) // Display the Dialog with the ListBox
 
Comment: ListBox selection is returned to SELECTED_VALUES variable!
MessageBox: Debug, ListBox selection:$NEWLINE$$SELECTED_VALUES$
 
Set Variable ITEMS_SELECTED to 0
Set Variable EQUALITY to FALSE
 
for each Element ELEMENT in $NEWLINE$ delimited Collection of $SELECTED_VALUES$ do
 ITEMS_SELECTED = $ITEMS_SELECTED$ + 1
 if Variable ELEMENT Equals DSN2
   Set Variable EQUALITY to TRUE
 end
next
 
MessageBox: Debug, ITEMS_SELECTED = $ITEMS_SELECTED$$NEWLINE$EQUALITY = $EQUALITY$
 
Terminate Installation

The same code snippet as InstallAware Clipboard format

Code: Select all
