在字段中使用字符串替换/正则表达式来获取rte字段

Question

I want to cutoff everything but the first paragraph from an rte field for an excerpt:

20 = HTML
20.value.field = tx_myextention_field
20.value.parseFunc < lib.parseFunc_RTE
20.wrap = <p class="claim-long">|</p>
20.stdWrap.replacement {
  10 {
    search = /^(.*?\/p).*$/m
    replace = \1>
    useRegExp = 1
 }
}

Why is this regex not working? Or is there a better solution?

Answer 1

You could use stdWrap.cropHTML to achieve a similar effect. It would also shorten a long first paragraph, and use more than one paragraph, if the first one is too short. But maybe thats desirable in your situation?
