$ jq -r '.[] | .denotations | .[] | select(.obj=="drug") | .span | [.begin,.end] | @tsv'
我可以使用上述jq命令从上述URL中提取以下信息。
377 387
562 579
584 602
659 676
681 699
919 936
941 959
1032 1049
1054 1072
但是我真正需要的输出如下。
最后一列只是text从begin+1到end的子字符串（假设text中的字符串从1开始索引。
我不知道如何仅使用jq提取此信息，因为它涉及到获取一个父级同级元素和另一个父级同级元素的子字符串。有人可以告诉我如何以这种格式提取输出吗？谢谢。

"project": "BERN","sourcedb": "PubMed","sourceid": "32818866","text": "Identification of two bitter components in Zanthoxylum bungeanum Maxim. and exploration of their bitter taste mechanism through receptor hTAS2R14. Bitterness is an inherent organoleptic characteristic affecting the flavor of Zanthoxylum bungeanum Maxim. In this study,the vital bitter components of Z. bungeanum were concentrated through solvent extraction,sensory analysis,silica gel chromatography,and thin-layer chromatographic techniques and subsequently identified by UPLC-Q-TOF-MS. Two components with the highest bitterness intensities (BIs),such as 7-methoxycoumarin and 8-prenylkaempferol were selected. The bitter taste perceived thresholds of 7-methoxycoumarin and 8-prenylkaempferol were 0.062 mmol/L and 0.022 mmol/L,respectively. Moreover,the correlation between the contents of the two bitter components and the BIs of Z. bungeanum were proved. The results of siRNA and flow cytometry showed that 7-methoxycoumarin and 8-prenylkaempferol Could activate the bitter receptor hTAS2R14. The results concluded that 7-methoxycoumarin and 8-prenylkaempferol contribute to the bitter taste of Z. bungeanum.","denotations": [

解决方法
假设所需输出的第一列是“ sourceid”，我们可以按以下方式调整您的解决方案：
.[]
| .sourceid as $id
| .text as $text
| .denotations[]
| select(.obj=="drug")
| .span
| [$id,.begin,.end,$text[.begin : .end] ]
| @tsv
