How to replace Quotation Marks of InfoType from String/Text?

[Momar]

How can I remove the Quotation Mark value of InfoType from Text/String. Like avatar_head="value"

I want all avatar_head="any_value" to change to avatar_head=""

like for example this Text:

<ITEM id="540001" name="Ceremonial Dress (a.Men)" type="avatar" slot="avatar" avatar_head="eq_head_12"
avatar_chest="eq_chest_16" avatar_hand="eq_hands_17" avatar_legs="eq_legs_16" avatar_feet="eq_feet_16"
totalpoint="0" hp="14" ap="52" weight="33" maxwt="0"
res_sex="m" res_level="2" bt_price="500000" iscashitem="true" desc="Ceremonial Dress that the general ranks of the Empire wear at important ceremonies." />
<ITEM id="540501" name="Ceremonial Dress (a.Women)" type="avatar" slot="avatar" avatar_head="eq_head_05"
avatar_chest="eq_chest_long002" avatar_hand="eq_hands_leather001" avatar_legs="eq_legs_014" avatar_feet="eq_feets_014"
totalpoint="0" hp="14" ap="52" weight="33" maxwt="0"
res_sex="f" res_level="2" bt_price="500000" iscashitem="true" desc="Ceremonial Dress that the general ranks of the Empire wear at important ceremonies." />

<ITEM id="540002" name="Adventurer (a.Men)" type="avatar" slot="avatar" avatar_head="eq_head_16"
avatar_chest="eq_chest_10" avatar_hand="eq_hands_09" avatar_legs="eq_legs_07" avatar_feet="eq_feet_08"
totalpoint="0" hp="5" ap="39" weight="24" maxwt="0"
res_sex="m" res_level="0" bt_price="500000" iscashitem="true" desc="Recommended for novice adventurers who hate outfits with heavy equipment." />
<ITEM id="540502" name="Adventurer (a.Women)" type="avatar" slot="avatar" avatar_head="eq_head_13"
avatar_chest="eq_chest_14" avatar_hand="eq_hands_05" avatar_legs="eq_legs_006" avatar_feet="eq_feets_006"
totalpoint="0" hp="5" ap="39" weight="24" maxwt="0"
res_sex="f" res_level="0" bt_price="500000" iscashitem="true" desc="Recommended for novice adventurers who hate outfits with heavy equipment." />

Please help, thank advance.
I am sorry if I ask here because I can't find a solution in Mr. Google.

One way will be to use regular expression

Another way - use strpos() and find the start/end position of the text that you want to replace and then do a substr_replace()
