XML Search for Dialog

[trevrobwhite]

I have built a new project in Advanced Installer upgrading an existing MSI, in the [APPDIR] I have a config file in XML format which may or may not ready exist, I'm trying to use the Search functionality to pre-populate the dialog should the values already exist.

The trouble I'm having is the layout of the XML file (which I've included a sample below), I've trying to get the ServerIP, SiteName and ProjectName and store the value in the Property, I've setup a search using the type Attribute Name and result type attribute value but it's not matching, I assume because the value is actually a child or the parent, I cannot use Index because the multiple setting values can be in any orders.

Any ideas how I can achieve this?

Thanks in advance.

Hello and welcome to our forums,

Are those values added in the XML file as properties (e.g. inserted by the user through dialog controls during the first install)?

If that is the case, you could set, in the older version, those properties as "persistent" properties. For more information about this, please have a look over the "How do I make the properties in the package keep their values during Maintenance or Upgrade?" article.

If this is not the case, please let me know so I can try to assist you with your scenario (the XML search).

Best regards,
Catalin

Hi Catalin,
The file and values usually exist, but for a new install advanced installer populates them, so I'm trying to use XML Search to bring in the values and populate the dialog where a system is already setup and where it's not the user can specify the properties on the command line to msiexec or use the dialog.
Many thanks.

Hello,

In order to achieve what you want, the XML Search may look as it follows:

If your XML file is located in APPDIR, an extra step might be required here:

- please go to "Table Editor" page

- change the sequence of "AI_XmlLocator" action from "101" to "1005"

Hope this helps.


Best regards,

Perfect many thanks, I will try this out.

I wanted to ask if I want to capture multiple values can I do this in one search or do I need separate ones?

To get ServerIP & SiteName

Many thanks.

Hello,

You are always welcome!

I wanted to ask if I want to capture multiple values can I do this in one search or do I need separate ones?

I'd suggest having a search for each element.
