by default awk expects a file as input but modHTML is a (string) variable; to have awk process a variable you can use a here-string to simulate feeding the string as a file to awk, eg: awk '/Update: /{p=1}p' <<< "$modHTML"
modHTML="xmllint --nowarning ..." is assigning the string xmllint --nowarning ... to modHTML when what you really want is to run the xmllint call and store the results in the modHTML variable, eg, modHTML=$(xmllint --nowarning ...)
Rolling these changes into OP's current code:
for mod in "${activeModList[@]}"
do
modDirectory="modHTML/$mod"
modHTML=$(xmllint --nowarning --html --xpath "/html/body/div[1]/div[7]/div[4]/div[1]/div[4]/div[11]/div[1]/div[2]/div[1]" "$modDirectory.html")
lastUpdateTime=$(awk '/Update: /{p=1}p' <<< "$modHTML")
# uncomment following line to assist with debugging; this will
# show you exactly what's stored in the variables thus allowing
# you to verify if your code is doing what you think it's doing
# typeset -p modHTML lastUpdateTime
echo "$mod last updated: $lastUpdateTime"
done
NOTES:
I don't use xmllint so I can't comment on whether or not this is a valid call but at least the proposed code changes should allow the OP to get a bit closer to the desired result
the awk call can probably be tweaked to provide a more compact answer but I'll leave that up to the OP to work on (once we get past the syntax errors and start generating actual output)

当前代码存在一些问题：
awk需要一个文件作为输入，但modHTML是一个（字符串）变量；要让awk处理变量，您可以使用此处字符串来模拟将字符串作为文件提供给awk，例如：awk '/Update: /{ p=1}p' <<< "$modHTML"modHTML="xmllint --nowarning ..."正在将字符串xmllint --nowarning ...分配给modHTML< /code> 当您真正想要的是运行xmllint调用并将结果存储在modHTML变量中时，例如modHTML=$(xmllint --nowarning ...)将这些更改滚动到OP的当前代码：
注释：
xmllint，因此我无法评论这是否是有效的调用，但至少建议的代码更改应该允许OP为了更接近期望的结果，awk调用以提供更紧凑的答案，但我将把它留给OP来处理（一旦我们通过了语法错误并开始生成实际输出）Couple issues with the current code:
