Check-AppRepository

By Mell Rosandich

-------------------------------------------------------

Setting up System values

-------------------------------------------------------

<basefolderpath>C:\Users\ServerAdmin\Desktop\AppVault</basefolderpath>

<datfolderpath>C:\Users\ServerAdmin\Desktop\dats</datfolderpath>

</system>

basefolderpath - where all doaloaded app are stored

datfolderpath - date file location, keeps versions and errors in files

-------------------------------------------------------

Setting up applications

-------------------------------------------------------

Each app you want to keep updated you need a appitem node in the applist.xml (or what ever file you pass as the config).

<checkdownloadurl>http://www.7-zip.org/download.html</checkdownloadurl>

<overridesavepath uncompress="no">C:\Users\ServerAdmin\Desktop\AppVault\test</overridesavepath>

</appitem>

The way the script works is as follows:

checkversionurl - this node contains the http link to the site with the version number of the application

checkversionregex matchnumber="1" - When the URL is pulled we regex with this expression and take the matchednumer="which match by regex" and this is how we get version

checkdownloadurl - A url where the donload might be

checkdownloadregex matchnumber="1"- a regex to fetch nother link to the down load matchnumber="which match by regex" to use for the dowload, can go 1 level deeper

downloadurl use="checkdownloadurl" - when set to use "checkdownloadurl" nodes

[or]

downloadurl usereg="no" - the URL defined here is a direct link to the files.

[or]

downloadurl use="checkdownloadurl" usereg="yes" - we now have another page with a direct download URL and must regex to get it.

downloadurlregex matchnumber="1" - final regex to get the URL for download.

saveasname useurlpart="yes" - no data need will use the name of the file feched from the URL

saveasname useurlpart="no" - what ever you want to name the file

overridesavepath - if set will override the path where the file will be saved

saverelativepath - save to the location set in the system.basefolderpath \ appName\

Sample 1 Smartermail, direct download, version is regex

<appname>SmarterMail9</appname>

<checkversionurl>http://smartertools.com/smartermail/releasenotes/v9.aspx</checkversionurl>

<downloadurl usereg="no">http://smartertools.com/Download.aspx?Product=SmarterMail&File=MSIInstaller&Version=9&Location=Primary</downloadurl>

<saveasname useurlpart="no">Smartermail9.msi</saveasname>

<saverelativepath uncompress="no">SmarterMail9</saverelativepath>

</appitem>

sample 2, notepad++, download URL changes per version. Version is regex

<appname>notepad</appname>

<checkversionurl>http://notepad-plus-plus.org/</checkversionurl>

<checkversionregex matchnumber="2"><![CDATA[<a.*>(.*)Current Version.*<span>(.*)</span>]]></checkversionregex>

<checkdownloadurl>http://notepad-plus-plus.org/</checkdownloadurl>

<checkdownloadregex matchnumber="1" ><![CDATA[<a.*?href="(.*)".*?>.*Current Version.*<span>(.*)</span>]]></checkdownloadregex>

<downloadurlregex matchnumber="1"><![CDATA[<a.*?href="(.*)".*?>.* zip package</a>]]></downloadurlregex>

<saverelativepath uncompress="yes">NotePad</saverelativepath>

</appitem>
