Hi,

I am trying to determine the path name for nodes that are children of categories so I can extract the node data and use some of it within a dice roll. The database structure in question looks like this:

<item>
<category name="Armor" baseicon="0" decalicon="0">
<category name="Gear" baseicon="0" decalicon="0">
<category name="Weapons" baseicon="0" decalicon="0">
<id-00001>
<accuracy type="string">Ballistic</accuracy>
<apvalue type="string">2</apvalue>
<armorarms type="number">0</armorarms>
<armorfeet type="number">0</armorfeet>
<armorhands type="number">0</armorhands>
<armorhead type="number">0</armorhead>
<armorlegs type="number">0</armorlegs>
<armortorso type="number">0</armortorso>
<availability type="string">D / B-B-B / D</availability>
<concealability type="string">All</concealability>
<cost type="string">75</cost>
<damage type="string">5</damage>
<description type="formattedtext">
<p></p>
</description>
<dmgspecial type="string">Splash</dmgspecial>
<locked type="number">1</locked>
<maxammo type="string">20</maxammo>
<name type="string">Needler Rifle</name>
<programmu type="string">0</programmu>
<programstr type="string">0</programstr>
<range type="string">5/14/30/40</range>
<reliability type="string">Average</reliability>
<rof type="string">1</rof>
<subtype type="string">Rifle</subtype>
<type type="string">Weapon</type>
<weight type="number">1</weight>
</id-00001>
<id-00003>
<accuracy type="string">Ballistic</accuracy>
<apvalue type="string">3</apvalue>
<armorarms type="number">0</armorarms>
<armorfeet type="number">0</armorfeet>
<armorhands type="number">0</armorhands>
<armorhead type="number">0</armorhead>
<armorlegs type="number">0</armorlegs>
<armortorso type="number">0</armortorso>
<availability type="string">C / C-B-C / C</availability>
<concealability type="string">LYRAN ALLIANCE</concealability>
<cost type="string">60</cost>
<damage type="string">4</damage>
<description type="formattedtext">
<p></p>
</description>
<dmgspecial type="string">None</dmgspecial>
<isidentified type="number">1</isidentified>
<locked type="number">1</locked>
<maxammo type="string">8</maxammo>
<name type="string">M&amp;G Service Auto-Pistol</name>
<programmu type="string">0</programmu>
<programstr type="string">0</programstr>
<range type="string">5/20/40/85</range>
<reliability type="string">Average</reliability>
<rof type="string">1</rof>
<subtype type="string">Pistol</subtype>
<type type="string">Weapon</type>
<weight type="number">0.65</weight>
</id-00003>

I can get the details of the category using the getChildCategories function but I am struggling to get the path name for the next level. The code I am using to see what the function retruns is:

for k, v in pairs(DB.getChildCategories("item")) do
-- rCategory = DB.getChildCategories("item");
sCategoryName = DB.getValue(k);
Debug.console("Weapon Name = ",k,v,sCategoryName);
end


The debug report for this is:

[14.10.2020 07:12:18] Runtime Notice: s'Item category = ' | { #1 = { s'decal' = #0, s'base' = #0, s'name' = s'' }, #2 = { s'decal' = #0, s'base' = #0, s'name' = s'Armor' }, #3 = { s'decal' = #0, s'base' = #0, s'name' = s'Gear' }, #4 = { s'decal' = #0, s'base' = #0, s'name' = s'Weapons' } }
[14.10.2020 07:12:18] Runtime Notice: s'Weapon Name = ' | #1 | { s'decal' = #0, s'base' = #0, s'name' = s'' } | nil
[14.10.2020 07:12:18] Runtime Notice: s'Weapon Name = ' | #2 | { s'decal' = #0, s'base' = #0, s'name' = s'Armor' } | nil
[14.10.2020 07:12:18] Runtime Notice: s'Weapon Name = ' | #3 | { s'decal' = #0, s'base' = #0, s'name' = s'Gear' } | nil
[14.10.2020 07:12:18] Runtime Notice: s'Weapon Name = ' | #4 | { s'decal' = #0, s'base' = #0, s'name' = s'Weapons' } | nil


How can I translate this into a path name so I can extract, say, the name and range strings from a node in the weapon category. I have tried using getValue and getChildren functions but can't get them to work.

Any help would be appreciated.

Use getChildren, not getChildCategories.

https://fantasygroundsunity.atlassian.net/wiki/spaces/FGU/pages/4063529/DB#getChildren

getChildren will return a LUA table with databasenode entries pointing to the id-XXXXX nodes.

Then use "DB.getValue(v,"name")" to get the value of the name node within (assuming you’re using "for k, v in pairs" to step through them).

Thanks Trenloe, I will give this a go this evening.

This has worked. Simple really. I was trying to over complicate things.

Thanks again Trenloe.

Now to extract the data I need.
