Problem changing a value

[JymBoe]

I'm having trouble with my mod code can anyone suggest a fix?

Here's the stock items.xml:

<item name="ammoDartIron">
    <property name="Extends" value="ammoArrowIron" param1="HandMeshfile"/>
    <property name="Meshfile" value="Entities/Electrical/steel_dartPrefab"/>
    <property name="HoldType" value="45"/>
    <property name="HandMeshfile" value="#Other/Items?Misc/sackPrefab.prefab"/>
    <property name="DropMeshfile" value="#Other/Items?Misc/sack_droppedPrefab.prefab"/>
    <property name="Stacknumber" value="500"/> <!-- STK ammo -->
    <property name="EconomicValue" value="34"/>
    <property name="EconomicBundleSize" value="10"/>
    <property name="DisplayType" value="ammoDart"/>
    <property class="Action1">
        <property name="Velocity" value="55"/>
        <property name="Gravity" value="-4"/>
        <property name="LifeTime" value="2"/>
    </property>
    <property class="Attributes">
        <property name="EntityDamage" value="22,45"/>
        <property name="BlockDamage" value="3,8"/>
    </property>
    <effect_group name="ammoDartIron" tiered="false">
        <passive_effect name="EntityDamage" operation="base_set" value="45"/>
        <passive_effect name="BlockDamage" operation="base_set" value="2"/>
        <passive_effect name="DamageModifier" operation="perc_set" value=".1" tags="wood"/>
        <passive_effect name="DamageModifier" operation="perc_set" value="0" tags="earth,metal,cloth,stone"/>
        <passive_effect name="ProjectileVelocity" operation="base_set" value="55"/>
    </effect_group>
</item>

Here's my mod items.xml code:

<set xpath="/items/item[@name='ammoDartIron']/effect_group[@name='ammoDartIron']/passive_effect[@name='EntityDamage']/operation[@name='base_set']/@value">500</set>

Here's the error from the log:

WRN XML patch for "items.xml" from mod "JymBoe" did not apply: <set xpath="/items/item[@name='ammoDartIron']/effect_group[@name='ammoDartIron']
        /passive_effect[@name='EntityDamage']/operation[@name='base_set']/@value"

Your XPath isn't correct. "operation" is an attribute, not a tag. So it would be this:

 

  <set xpath="/items/item[@name='ammoDartIron']/effect_group[@name='ammoDartIron']/passive_effect[@name='EntityDamage' and @operation='base_set']/@value">500</set>

Thanks khzmusik, the code you wrote works and explains some other problems I've encountered.
